Angle of refraction of ray of light travelling from air to water is , then the angle between incident ray and surface of separation of air and glass of R.I. 1.3 is :

Answer: (C)

Solution

With μ = 1.3, sin i = 1.3 sin30° = 0.65; the ray makes angle 90° − i with the surface, so (a) is the angle of
