1. A right-triangular prism has edge lengths of 4.2 cm, 4.0 cm, and 5.8 cm. A ray of red light in the air hits the 4.0 cm edge at an incident angle of 0.0. The prism is made of crown glass, which has an index of refraction of 1.49 for red light. (8 points) 1. Calculate the angle of deviation of the light beam from its original path after it leaves the prism. The angle of deviation is the angle between the incident ray and the final outgoing ray. 2. Is it possible for the incident angle (on the same side) to be adjusted such that the light will experience total internal reflection when it reaches the other side of the prism? If so, what angle would you use for the incident ray? 4.0 cm 4.2 cm 5.8 cm
