Class 6 Science Chapter 8 Case Based Questions - Light, Shadow and Reflections

Sarah is conducting an experiment with different objects to understand the properties of light. She has a wooden box, a glass pane, and a candle. She is using a source of light to observe the behavior of these objects.

Q1: What type of object is the wooden box in this scenario, and why? Ans: The wooden box is an opaque object because it does not allow light to pass through it. Q2: If Sarah observes that she can see through the glass pane clearly, what type of object is it, and why? Ans: The glass pane is a transparent object because it allows light to pass through it clearly. Q3: How does the behavior of the candle differ from the wooden box and the glass pane in terms of emitting light? Ans:   The candle is a luminous object because it emits its own light. Q4: Which of the following objects is an example of a translucent object? (a)  Wooden box (b)  Glass pane (c) Candle Ans:   (b) Q5: What is the primary characteristic that distinguishes a luminous object from a non-luminous object?

Mark is using a pinhole camera to capture images. He is experimenting with the camera's focus and understanding the principles behind it.

Q6: Explain how the image formed by Mark's pinhole camera is different from the actual object in terms of size and orientation. Ans:   The image formed by Mark's pinhole camera is inverted and smaller in size compared to the actual object. Q7: Describe the steps Mark should follow to make a pinhole camera. Ans: Steps to make a pinhole camera:

• Take two rectangular boxes that fit into one another without any gap.
• Cut open one side of each box.
• Make a small hole in the larger box at the center of the closed end opposite the side that has been cut open.
• Cut a square of side five centimeters in the smaller box in the closed end opposite the side that has been cut open.
• Cover this square with tracing paper.
• Slide the smaller box into the larger box, ensuring that the pinhole and the tracing paper are in line with one another but at opposite ends.
• Slide the smaller box to adjust the focus.

Q8: Why is it mentioned that "the image is not clear" in the context of a pinhole camera? Ans:   The image is not clear because the pinhole camera uses a small hole to form the image, resulting in limited light and reduced clarity. Q9: What is the principle on which a pinhole camera works? (a) The principle of reflection of light. (b)  The principle of refraction of light. (c)  The principle of straight-line propagation of light. Ans:   (c) Q10: Which type of surface reflects the entire light incident on it? (a) Transparent surface (b)  Opaque surface (c) Plane mirror surface Ans: (c)

A group of students is discussing the difference between shadows and images. They are using a mirror and a flashlight to observe and learn about these phenomena.

Q11: Explain the similarities and differences between shadows and images. Ans: Similarities:

• Both shadows and images require a source of light.
• They are formed when light interacts with objects.

Differences:

• Shadows are black and have no color, while images can be colorful.
• Shadows change in length with the position of the sun, while images in a mirror remain the same size.

Q12: Describe the setup and conditions required to observe a shadow and an image. Ans:   To observe a shadow, you need a source of light, an opaque object, and a screen. To observe an image in a mirror, you need a reflective surface and an object in front of it. Q13: Why do shadows change in length throughout the day, while images in a mirror do not? Ans: Shadows change in length throughout the day because of the changing angle and position of the sun. Images in a mirror do not change size.

A group of students is visiting an observatory, where they encounter a two-way mirror. They are curious about its functionality.

Q16: Explain how a two-way mirror works and its practical applications. Ans: A two-way mirror, also known as a one-way mirror, allows one side to act as a mirror (reflective) and the other side as plain glass (transparent). It is used for observing people without them knowing, such as in police stations or psychological institutions. Q17: Compare and contrast the behavior of a two-way mirror with a regular plane mirror. Ans:   Comparison with a regular plane mirror:

• A plane mirror is always reflective, whereas a two-way mirror can switch between reflective and transparent properties.

11. Tasty food is not always nutritious, and nutritious food may not always be tasty to eat. Comment with examples. Solution:

Tasty food is not always nutritious like, burgers, pizzas, chats, potato chips etc. are very tasty but not nutritious. These foods contain refined flour (Maida), spices and a lot of oil which is not good for health.

On the other hand, nutritious food may not always be tasty to eat like, boiled vegetables, pulses, leafy vegetables etc., which are not always tasty but are very good for health. These foods contain important nutrients (proteins, vitamins, minerals etc.) which help us to maintain our body strong and healthy.

12. While using iodine in the laboratory, some drops of iodine fell on Paheli’s socks, and some fell on her teacher saree. The drops of iodine on the saree turned blue-black, while their colour did not change on the socks. What can be the possible reason? Solution:

The saree of Paheli’s teacher would have contained starch. When starch is exposed to iodine solution, starch turns into blue-black, so the saree also turned blue-black. Paheli’s socks would not have contained starch and thus did not show any colour change.

13. Paheli and Boojho peeled some potatoes and cut them into small pieces. They washed and boiled them in water. They threw away the excess water and fried them in oil adding salt and spices. Although the potato dish tasted very good, its nutrient value was less. Suggest a method of cooking potatoes that will not lower the nutrients in them. Solution:

Potatoes are nutritious vegetables that provide carbohydrates, vitamins (especially vitamin C), minerals and dietary fibre. Consuming potatoes along with their skin (peel) provides extra dietary fibre and nutrients.

A method of cooking potatoes that will not lower their nutrient value is:

Wash the potatoes and cut them into thin slices. Cook the potatoes with some water along with a little amount of oil and by adding salt and spices. Cover the cooking pot while cooking. This method helps to conserve the nutrients of potatoes.

14. Paheli avoids eating vegetables but likes to eat biscuits, noodles and white bread. She frequently complains of stomach ache and constipation. What are the food items that she should include in her diet to get rid of the problem? Give a reason for your answer. Solution:

Paheli should include whole grains, whole pulses, fresh fruits and vegetables in her diet to get rid of her problems. These food items contain roughage (dietary fiber) which is lacking in Paheli’s diet.

Paheli should avoid eating biscuits, noodles and white bread as they are made up of refined flour (Maida) which does not contain any roughage or fiber. Roughage prevents constipation.

15. (a) List all those components of food that provide nutrients. (b) Mention two components of food that do not provide nutrients. Solution:

(a) Components of food that provide nutrients are carbohydrates, fats, proteins, vitamins and minerals.

(b) Components of food that do not provide nutrients are water and roughage.

16. ‘Minerals and vitamins are needed in very small quantities by our body as compared to other components, yet, they are an important part of a balanced diet’. Explain the statement. Solution:

Minerals and vitamins are needed in very small quantities but are essential for the normal functioning of our body. Because

(i) They are protective foods which help in protecting our body against diseases.

(ii) They help in maintaining the normal growth of our body.

(iii) They provide good immunity levels, which leads to good health.

17. ‘Water does not provide nutrients, yet it is an important component of food’. Explain. Solution:

Water is an important component of our food because

(i) Water helps carry nutrients from food to all cells in our body and oxygen to the brain.

(ii) Water helps in flushing out toxins and wastes in the form of urine and sweat.

(iii) Water allows the body to absorb and assimilate vitamins, minerals etc.

(iv) Water helps to regulate body temperature.

18. Boojho was having difficulty in seeing things in dim light. The doctor tested his eyesight and prescribed a particular vitamin supplement. He also advised him to include a few food items in his diet. (a) Which deficiency disease is he suffering from? (b) Which food component may be lacking in his diet? (c) Suggest some food items that he should include in his diet. (any four) Solution:

(a) Boojho is suffering from night blindness which results in difficulty of seeing things in dim light.

(b) Deficiency of vitamin A causes night blindness. Hence vitamin A might be lacking in his diet.

(c) In his diet, Boojho can include food items such as carrot, spinach, papaya, milk, green leafy, vegetables, fish oil, etc. which are rich in vitamin A.

Short Answer Questions                                                                               (3 Marks)

1. Who created the metric system and why?

Ans: In 1790, the French devised the metric system in order to establish a uniform system of measurement. Until then, different people employed various methods. For example, to measure distance, cubits, paces, foot, yards, and other units were used. There was no uniformity in measurement because each item had a different value. Furthermore, the value of each would vary depending on who was measuring. As a result, to assure homogeneity of measurements throughout different countries, regardless of their size and French introduced the metric system to the world.

2. The distance from Meena’s house to the playground is \[20\]paces. If one pace is equal to \[40\,cm\], what is the distance in SI units?

Ans: Given: The distance from Meena’s house to playground \[=\text{ }20\]paces 

$\because 1 pace = 40 cm$

Then, \[20 paces = 20 \times  40\] 

\[\text{= 800 cm}\]

\[\because \text{100 cm = 1 m}\]

Hence, \[\text{800 cm = 8 m}\]

Therefore, the distance from Meena’s house to the playground in SI units is \[\text{8m}\].

3. Keith requires \[5.6\] yards of cloth to get a suit stitched. What length of cloth does he require in metres if \[1\] yard is \[0.9\] metres?

Ans: Given: Keith requires \[5.6\] yards of cloth

\[\because \text{1 yard = 0}\text{.9 m}\]

Then, \[\text{5}\text{.6 yards = 5}\text{.6  }\!\!\times\!\!\text{  0}\text{.9}\]

\[\text{= 5}\text{.04 m}\]

Therefore, Keith requires \[\text{5}\text{.04 m}\]of cloth.

4. The length of the blackboard in Ajay’s class is \[4.5\] cubit. What is its length in SI units if  $ 1\text{cubit}=\text{ }45.72\text{cm} $ ?

Ans: Given: Length of the blackboard in Ajay’s class \[=\text{ }4.5\text{ cubit}\]

\[\because \text{1cubit = 45}\text{.72 cm}\]

Then, length of the blackboard \[=\text{ }4.5\text{ }\times \text{ }45.72\]

Ans: Motions can be divided into three categories:

Rectilinear Motion: 

An object moves in a straight path in this sort of motion.

The object's direction may change from time to time, but it always moves in a straight line.

Examples include a car travelling down a straight road, an aeroplane flying, and a ball rolling on the ground.

Circular Motion:

The object moves in a circular motion in this form of motion.

The object moves, but the distance between it and the origin remains constant. 

For example, clock hands, fan blades, windmill blades, and so on.

Periodic Motion:

In this form of motion, an item moves in a sequential manner.

A similar motion is repeated by the object on a regular basis. 

For example, swing movement, drumming, and so on.

2. Compare rectilinear motion with circular motion.

Ans: Comparisons between rectilinear and circular motion is as given below,

3. Classify the following as circular, periodic or rectilinear motion: Playing a mridangam, Carousel, Swing, Speed boat racing ahead, \[\mathbf{100m}\] dash, Shuttlecock during a game of badminton, weather vane, rocking chair, a penalty kick in a game of football, aeroplane during take-off.

Artificial intelligence  is being used in healthcare for everything from answering patient questions to assisting with surgeries and developing new pharmaceuticals.

According to  Statista , the artificial intelligence (AI) healthcare market, which is valued at $11 billion in 2021, is projected to be worth $187 billion in 2030. That massive increase means we will likely continue to see considerable changes in how medical providers, hospitals, pharmaceutical and biotechnology companies, and others in the healthcare industry operate.

Better  machine learning (ML)  algorithms, more access to data, cheaper hardware, and the availability of 5G have contributed to the increasing application of AI in the healthcare industry, accelerating the pace of change. AI and ML technologies can sift through enormous volumes of health data—from health records and clinical studies to genetic information—and analyze it much faster than humans.

Healthcare organizations are using AI to improve the efficiency of all kinds of processes, from back-office tasks to patient care. The following are some examples of how AI might be used to benefit staff and patients:

• Administrative workflow:  Healthcare workers spend a lot of time doing paperwork and other administrative tasks. AI and automation can help perform many of those mundane tasks, freeing up employee time for other activities and giving them more face-to-face time with patients. For example, generative AI can help clinicians with note-taking and content summarization that can help keep medical records as thoroughly as possible. AI might also help with accurate coding and sharing of information between departments and billing.
• Virtual nursing assistants:  One study found that  64% of patients  are comfortable with the use of AI for around-the-clock access to answers that support nurses provide. AI virtual nurse assistants—which are AI-powered chatbots, apps, or other interfaces—can be used to help answer questions about medications, forward reports to doctors or surgeons and help patients schedule a visit with a physician. These sorts of routine tasks can help take work off the hands of clinical staff, who can then spend more time directly on patient care, where human judgment and interaction matter most.
• Dosage error reduction:  AI can be used to help identify errors in how a patient self-administers medication. One example comes from a study in  Nature Medicine , which found that up to 70% of patients don’t take insulin as prescribed. An AI-powered tool that sits in the patient’s background (much like a wifi router) might be used to flag errors in how the patient administers an insulin pen or inhaler.
• Less invasive surgeries:  AI-enabled robots might be used to work around sensitive organs and tissues to help reduce blood loss, infection risk and post-surgery pain.
• Fraud prevention:  Fraud in the healthcare industry is enormous, at $380 billion/year, and raises the cost of consumers’ medical premiums and out-of-pocket expenses. Implementing AI can help recognize unusual or suspicious patterns in insurance claims, such as billing for costly services or procedures that are not performed, unbundling (which is billing for the individual steps of a procedure as though they were separate procedures), and performing unnecessary tests to take advantage of insurance payments.

A recent study found that  83% of patients  report poor communication as the worst part of their experience, demonstrating a strong need for clearer communication between patients and providers. AI technologies like  natural language processing  (NLP), predictive analytics, and  speech recognition  might help healthcare providers have more effective communication with patients. AI might, for instance, deliver more specific information about a patient’s treatment options, allowing the healthcare provider to have more meaningful conversations with the patient for shared decision-making.

According to  Harvard’s School of Public Health , although it’s early days for this use, using AI to make diagnoses may reduce treatment costs by up to 50% and improve health outcomes by 40%.

One use case example is out of the  University of Hawaii , where a research team found that deploying  deep learning  AI technology can improve breast cancer risk prediction. More research is needed, but the lead researcher pointed out that an AI algorithm can be trained on a much larger set of images than a radiologist—as many as a million or more radiology images. Also, that algorithm can be replicated at no cost except for hardware.

An  MIT group  developed an ML algorithm to determine when a human expert is needed. In some instances, such as identifying cardiomegaly in chest X-rays, they found that a hybrid human-AI model produced the best results.

Another  published study  found that AI recognized skin cancer better than experienced doctors.  US, German and French researchers used deep learning on more than 100,000 images to identify skin cancer. Comparing the results of AI to those of 58 international dermatologists, they found AI did better.

As health and fitness monitors become more popular and more people use apps that track and analyze details about their health. They can share these real-time data sets with their doctors to monitor health issues and provide alerts in case of problems.

AI solutions—such as big data applications, machine learning algorithms and deep learning algorithms—might also be used to help humans analyze large data sets to help clinical and other decision-making. AI might also be used to help detect and track infectious diseases, such as COVID-19, tuberculosis, and malaria.

One benefit the use of AI brings to health systems is making gathering and sharing information easier. AI can help providers keep track of patient data more efficiently.

One example is diabetes. According to the  Centers for Disease Control and Prevention , 10% of the US population has diabetes. Patients can now use wearable and other monitoring devices that provide feedback about their glucose levels to themselves and their medical team. AI can help providers gather that information, store, and analyze it, and provide data-driven insights from vast numbers of people. Using this information can help healthcare professionals determine how to better treat and manage diseases.

Organizations are also starting to use AI to help improve drug safety. The company SELTA SQUARE, for example, is  innovating the pharmacovigilance (PV) process , a legally mandated discipline for detecting and reporting adverse effects from drugs, then assessing, understanding, and preventing those effects. PV demands significant effort and diligence from pharma producers because it’s performed from the clinical trials phase all the way through the drug’s lifetime availability. Selta Square uses a combination of AI and automation to make the PV process faster and more accurate, which helps make medicines safer for people worldwide.

Sometimes, AI might reduce the need to test potential drug compounds physically, which is an enormous cost-savings.  High-fidelity molecular simulations  can run on computers without incurring the high costs of traditional discovery methods.

AI also has the potential to help humans predict toxicity, bioactivity, and other characteristics of molecules or create previously unknown drug molecules from scratch.

As AI becomes more important in healthcare delivery and more AI medical applications are developed, ethical, and regulatory governance must be established. Issues that raise concern include the possibility of bias, lack of transparency, privacy concerns regarding data used for training AI models, and safety and liability issues.

“AI governance is necessary, especially for clinical applications of the technology,” said Laura Craft, VP Analyst at  Gartner . “However, because new AI techniques are largely new territory for most [health delivery organizations], there is a lack of common rules, processes, and guidelines for eager entrepreneurs to follow as they design their pilots.”

The World Health Organization (WHO) spent 18 months deliberating with leading experts in ethics, digital technology, law, and human rights and various Ministries of Health members to produce a report that is called  Ethics & Governance of Artificial Intelligence for Health . This report identifies ethical challenges to using AI in healthcare, identifies risks, and outlines six  consensus principles  to ensure AI works for the public’s benefit:

• Protecting autonomy
• Promoting human safety and well-being
• Ensuring transparency
• Fostering accountability
• Ensuring equity
• Promoting tools that are responsive and sustainable

The WHO report also provides recommendations that ensure governing AI for healthcare both maximizes the technology’s promise and holds healthcare workers accountable and responsive to the communities and people they work with.

AI provides opportunities to help reduce human error, assist medical professionals and staff, and provide patient services 24/7. As AI tools continue to develop, there is potential to use AI even more in reading medical images, X-rays and scans, diagnosing medical problems and creating treatment plans.

AI applications continue to help streamline various tasks, from answering phones to analyzing population health trends (and likely, applications yet to be considered). For instance, future AI tools may automate or augment more of the work of clinicians and staff members. That will free up humans to spend more time on more effective and compassionate face-to-face professional care.

When patients need help, they don’t want to (or can’t) wait on hold. Healthcare facilities’ resources are finite, so help isn’t always available instantaneously or 24/7—and even slight delays can create frustration and feelings of isolation or cause certain conditions to worsen.
