Answer 2

hey buddy,

there are some question of light chapter of class 10th..

1) applications of concave and concave mirror

2) State the laws of refraction of light. If the speed of light in vacuum is 3X108 ms-1, find the speed of light in a medium of absolute refractive index 1.5.

3) 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

4)The power of the lens is -4.0D. What is the nature of this lens?

5) Draw ray diagrams to represent the nature, position and relative size of the image formed by a convex lens for the object placed:

(a) at 2F1

(b) between F1 and the optical centre O of lens:

these are quite important question you can try them.

hope it's helpful to you

thank you..
