Red light is incident in the air on a 30- 60- 90(degree) prism as shown in the figure. The incident beam is directed at an angle of 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.
(a ) What is , the angle the beam in the prism makes with the horizontal axis?
(b) What is n, the index of refraction of the prism for red light?
