Question

A ray of light is incident on the surface of a block of clear ice at an angle of 44.0° with the normal. Part of the light is reflected and part is refracted. Find the angle between the reflected and refracted light.
°

Answer 1

The angle of incidence is 44 ^o

the refraction index of ice is n₂=1.31

the refraction index of air is n₁=1.00

We know that

or,

or,

The angle between the reflected and refracted light is given by

or,

therefore, the angle between the reflected and refracted light is 192^o
