2. A triangular prism is made of glass (n1=1.50). The cross-section of the prism is a right triangle with dimensions a=5.0cm. b=12.0cm, and c=13.0cm. A ray of light strikes the hypotenuse face of the prism, precisely at its center and with normal incidence. The ray passes through the prism until it strikes another face with angle of incidence theta1. It then passes back into the air (n2=1.00) with angle of refraction theta2.

What is theta2?

For the limit check, investigate what happens to theta2 if surrounding air is replaced with another medium whose index of refraction is close to that of glass.
