Ver 03h 03 Prism Prism пр 60° np = 1.58 60° /52.5° 52.5° Problem 2: Light is incident from air onto a equilateral glass prism at a 45° angle to one face, as shown in the figure above on the left. Calculate 04, the angle at which light emerges from the opposite face. Assume that no = 1.58 for the prism. Answer: 04 = 60.46°. Problem 3: Light is incident from air onto a glass prism at a 45° angle to one face, as shown in the figure above on the right. This light ray strikes the face at the opposite side at 03, the critical angle for total internal reflection. The prism apex angle (at the top) is o = 75°. What is np, the index of refraction of the prism? Answer: np = 1.41.
