In CBSE Class 10 Science Paper, Students will have to answer some questions based on Assertion and Reason . There will be a few questions based on case studies and passage-based as well. In that, a paragraph will be given.
Here we are providing you with Class 10 Science Chapter 10 Light Reflection and Refraction Case Study Questions, by practicing these Case Study and Passage Based Questions will help you in your Class 10th Board Exam.
Here, we have provided case-based/passage-based questions for Class 10 Science Chapter 10 Light Reflection and Refraction
Case Study/Passage-Based Questions
Question 1:
The spherical mirror forms different types of images when the object is placed at different locations. When the image is formed on the screen, the image is real and when the image does not form on-screen, the image is virtual. When the two reflected rays meet actually, the image is real and when they appear to meet, the image is virtual. A concave mirror always forms a real and inverted image for different positions of the object. But if the object is placed between the focus and pole, the image formed is virtual and erect. A convex mirror always forms a virtual, erect, and diminished image. A concave mirror is used as a doctor’s head mirror to focus light on body parts like eyes, ears, nose, etc., to be examined because it can form erect and magnified images of the object. The convex mirror is used as a rear view mirror in automobiles because it can form a small and erect image of an object.
(i) When an object is placed at the center of curvature of a concave mirror, the image formed is
(a) larger than the object | (b) smaller than the object |
(c) same size as that of the object | (d) highly enlarged. |
Answer: (c) same size as that of the object
(ii) No matter how far you stand from a mirror, your image appears erect. The mirror is likely to be
(a) plane | (b) concave |
(c) convex | (d) either plane or convex. |
Answer: (d): The image is erect in a plane mirror and also in a convex mirror, for all positions of the object.
(iii) A child is standing in front of a magic mirror. She finds the image of her head bigger, the middle portion of her body of the same size and that of the legs smaller. The following is the order of combinations for the magic mirror from the top.
(a) Plane, convex and concave | (b) Convex, concave and plane |
(c) Concave, plane and convex | (d) Convex, plane and concave |
Answer: (c) : As the image of head is bigger, the upper portion of magic mirror is concave. The middle portion of the image is of same size, so, middle portion of magic mirror is plane. Now, the image of legs looks smaller, therefore, the lower portion of magic mirror is convex.
(iv) To get an image larger than the object, one can use (a) convex mirror but not a concave mirror (b) a concave mirror but not a convex mirror (c) either a convex mirror or a concave mirror (d) a plane mirror.
Answer: (b) a concave mirror but not a convex mirror
(v) A convex mirror has wider field of view because (a) the image formed is much smaller than the object and large number of images can be seen (b) the image formed is much closer to the mirror (c) both (a) and (b) (d) none of these.
Answer: (c) both (a) and (b)
Question 2:
The lenses form different types of images when objects are placed at different locations. When a ray is incident parallel to the principal axis, then after refraction, it passes through the focus or appears to come from the focus.
When a ray goes through the optical center of the lens, it passes without any deviation. If the object is placed between the focus and the optical center of the convex lens, an erect and magnified image is formed.
As the object is brought closer to the convex lens from infinity to focus, the image moves away from the convex lens from focus to infinity. Also, the size of the image goes on increasing and the image is always real and inverted.
A concave lens always gives a virtual, erect, and diminished image irrespective of the position of the object.
(i) The location of image formed by a convex lens when the object is placed at infinity is (a) at focus (b) at 2F (c) at optical center (d) between Fand 2F
Answer: (a) at focus
(ii) When the object is placed at the focus of concave lens, the image formed is (a) real and smaller (b) virtual and inverted (c) virtual and smaller (d) real and erect
Answer: (b) virtual and inverted
(iii) The size of image formed by a convex lens when the object is placed at the focus of convex lens is (a) small (b) point in size (c) highly magnified (d) same as that of object
Answer: (c) highly magnified
(iv) When the object is placed at 2F in front of convex lens, the location of image is (a) at F (b) at 2 F on the other side (c) at infinity (d) between F and optical center
Answer: (b) at 2 F on the other side
(v) At which location of object in front of concave lens, the image between focus and optical centre is formed (a) anywhere between centre and infinity (b) at F (c) at 2F (d) infinity
Answer: (a) anywhere between centre and infinity

Q1: what are simple equations.
A1: Simple equations are mathematical statements that express equality between two expressions. They usually involve a variable (like x) and can be solved to find the value of the variable that makes the equation true.
A2: To solve a simple equation, you need to isolate the variable on one side of the equation. This can be done by performing the same mathematical operations on both sides of the equation, such as addition, subtraction, multiplication, or division.
A3: Simple equations usually have a single unique solution. However, certain types of equations, like identities, can have infinite solutions, but those are not typically covered under “simple equations” in Class 7.
A4: Learning simple equations is important because it forms the foundation for more advanced topics in algebra and mathematics. It helps in developing problem-solving skills and understanding how to work with variables and mathematical relationships.
A5: Simple equations can be used in various real-life situations, such as calculating expenses, determining distances, solving for unknown quantities in recipes, and even in basic physics problems involving speed, distance, and time.
A6: Common mistakes include not performing the same operation on both sides of the equation, incorrectly combining like terms, and forgetting to change the sign when moving terms from one side of the equation to the other.
A7: To master simple equations, students should focus on understanding the basic principles of balancing equations, practice regularly, and check their solutions by substituting the value back into the original equation to ensure it holds true.
A8: Students can practice effectively by solving a variety of problems, starting with simple ones and gradually moving to more complex equations. They can also use online resources, worksheets, and practice tests to reinforce their learning.
A9: We provide case study questions for CBSE Class 8 Maths on our website . Students can visit the website and practice sufficient case study questions and prepare for their exams. If you need more case study questions, then you can visit Physics Gurukul website. they are having a large collection of case study questions for all classes.
Gibbons are known as one of the most vocal non-human primates. They vocally advertise and reinforce their pair-bonds by singing complex duets, in which both the male and female perform a predetermined sex-specific set of song phrases, including the loud and elongated great-calls. Only females and sub-adult male gibbons have been previously observed performing great-calls. Once a male gibbon matures, he normally stops great-call production completely but continues singing other and less high-pitched song phrases. This case study describes a fully adult, castrated male lar gibbon (Hylobates lar, 32 years old, zoo-housed) who performs both male phrases of the duet, including the female great-call. The male regularly produced great-calls despite being in a, relatively weak, pair bond with a female conspecific. His great-calls adhered to the general structure of typical female great-calls but were shorter and had a lower maximum frequency. Notably, he produced these great-calls predominantly when the female was absent, especially when she was in their inside enclosure whilst he was outside. Behavioural observations indicate that the occurrence of great-calls by the male cannot be predicted based on pre-song behaviour or his interaction with the female. The recurrence of sub-adult singing behaviour in a fully grown adult is most likely due to his reduced testosterone levels. This study sheds light on the intricate dynamics of duetting and the unique occurrence of cross-sex song production in gibbons, emphasizing the complexity of pair-bond communication in this species.

Title: revisiting the graph reasoning ability of large language models: case studies in translation, connectivity and shortest path.
Abstract: Large Language Models (LLMs) have achieved great success in various reasoning tasks. In this work, we focus on the graph reasoning ability of LLMs. Although theoretical studies proved that LLMs are capable of handling graph reasoning tasks, empirical evaluations reveal numerous failures. To deepen our understanding on this discrepancy, we revisit the ability of LLMs on three fundamental graph tasks: graph description translation, graph connectivity, and the shortest-path problem. Our findings suggest that LLMs can fail to understand graph structures through text descriptions and exhibit varying performance for all these three fundamental tasks. Meanwhile, we perform a real-world investigation on knowledge graphs and make consistent observations with our findings. The codes and datasets are available.
