Answer
Angle of incidence is always greater than the angle of refraction
Reason — As light enters the denser medium, it bends towards the normal, resulting in a smaller angle of refraction compared to the angle of incidence.

A ray of light is incident normally on a plane glass slab. What will be (i) the angle of refraction and (ii) the angle of deviation for the ray?
An obliquely incident light ray bends at the surface due to change in speed, when passing from one medium to other. The ray does not bend when it is incident normally. Will the ray have different speed in the other medium?
