Exercise 56

A light ray traveling in air is incident on one face of a right-angle prism with index of refraction n = 1.50, as shown in Figure P22.54, and the ray follows the path shown in the figure. Assuming = 60.0° and the base of the prism is mirrored, determine the angle and the base of the prism is mirrored, determine the angle made by the outgoing ray with the normal to the right face of the prism.
