Question

A ray of light passes from glass into air. The angle of refraction will be:

(a) equal to the angle of incidence
(b) greater than the angle of incidence
(c) smaller than the angle of incidence
(d) 45° 

Solution

greater than the angle of incidence
Because when a light ray passes from denser medium to a rarer medium, it bends away from the normal.
