The prism shown in the figure is placed in air ( = 1) in the position shown. A light beam is incident on the left side (side AB) of the prism. The index of refraction of the prism for the
frequency of light used is p = 1.5.
a) Sketch in a diagram the direction of the light ray when it comes out of the other side
(side BC) of the prism. Justify your answer
b) Find the angle between the light ray and the dashed line when it comes out of side BC.
c) Find the angle that the corner B of the prism must be to have total internal reflection of
the light ray at side BC
