2. (25 points) Red light traveling in vacuum is incident on a glass prism with index of refraction n = 1.35 (see Figure 1). If the apex (top) angle of the prism is 90 and the other two internal angles are equal to one another then answer the following. Figure 1: Light incident on a prism a. (10 points) At what angle, 91 will the light be refracted such that it travels parallel to the bottom edge of the prism while it is traveling inside of the glass? b. (15 points] What is the maximum angle, 61, that will cause the light to undergo total internal reection at the right boundary of the prism
