Question

A ray of light travelling in air goes into water. The angle of refraction will be:

(a) 90°
(b) smaller than the angle of incidence
(c) equal to the angle of incidence
(d) greater than the angle of incidence

Open in App

Solution

(b) smaller than the angle of incidence
Because when a light ray passes from a rarer medium to a denser medium, it bends towards the normal.

Q. In the experiment to trace the path of a ray of light through a parallel sided glass slab, a student measured the angles of refraction for three different angles of incidence. He will find that:
(1) angle of refraction is always equal to the angle of incidence
(2) angle of refraction is always smaller than the angle of incidence
(3) angle of refraction is always greater than the angle of incidence
(4) angle of refraction can be smaller or greater than the angle of incidence depending on the refractive index of glass slab
