Question

Can someone give me questions on light class 10 physics​

Answer 1

Answer:

These are some important questions if you want to practice.

1. A concave lens has focal length of 20 cm. At what distance from the lens a 5 cm tall object be placed so that it forms an image at 15 cm from the lens? Also calculate the size of the image formed.
2. An object 50 cm tall is placed on the principal axis of a convex lens. Its 20 cm tall image is formed on the screen placed at a distance of 10 cm from the lens. Calculate the focal length of the lens.
3. Draw the ray diagram in each case to show the position and nature of the image formed when the object is placed:
4. (i) at the centre of curvature of a concave mirror
5. (ii) between the pole P and focus F of a concave mirror
6. (iii) in front of a convex mirror
7. (iv) at 2F of a convex lens
8. (v) in front of a concave lens
9. Draw ray diagrams to represent the nature, position and relative size of the image formed by a convex lens for the object placed:
10. (a) at 2F1
11. (b) between F1 and the optical centre O of lens
12. A ray of light, incident obliquely on a face of a rectangular glass slab placed in air, emerges from the opposite face parallel to the incident ray. State two factors on which the lateral displacement of the emergent ray depends.
