Light Passing Through Triangular Medium


A transparent object with an isosceles right triangular cross-section has an index of refraction n2 = 1.2, as shown in the diagram below.

A light beam in air is incident on this object, making an angle θin = 75° with respect to the x-axis, as shown. At what angle (with respect to the x-axis), θout, does the observer see the light beam exit the object?

θout = degrees
