Special Relativity

The theory of special relativity discusses how space and time are related to objects traveling along a straight line at a constant speed. Simply stated, as an object reaches the speed of light, its mass becomes infinite and it is unable to move faster than light. This interstellar speed limit has been the topic of much debate in astronomy, and also in science fiction when people consider how to fly over large distances.

Question

A ray of monochromatic light is incident perpendicularly on point A of a right circular semi-cylinder made of glass, of radius R, immersed in air, and of refractive index 1.2. When crossing it, this ray emerges at point B, under a theta angle, contained in the circular surface of the semi-cylinder, according to the figure below. What is the value of theta?
