Red light is incident in air on a 30-60-90 (degree) prism as shown. The incident beam is directed at an angle of Φ1 = 41.30 with respect to the horizontal and enters the prism at a height h = 17 cm above the base. The beam leaves the prism to the air at a distance d = 45.5 cm along the base as shown. What is n, the index of refraction of the prism for red light?
