In your laboratory you trace the path of light rays through a glass slab for different values of angle of incidence (`angle` i) and in each case measure the values of the corresponding angle of refraction (`angle` r) and angle of emergence (`angle` e). On the basis of your observation your correct conclusion is:

Options

A. `angle`i is more than `angle`r, but nearly equal to `angle`e
B. `angle`i is less than `angle`r, but nearly equal to `angle`e
C. `angle`i is more than `angle`e, but nearly equal to `angle`r
D. `angle`i is less than `angle`e, but nearly equal to `angle`r

Answer

A

Explanation

When a ray oflight passes through the glass slab, then the angle of incidence is found to be nearly equal to angle of emergence and greater than angle of refraction
