i = 90 - 30 - ϕ1 = 90 - 30 - 41.3 = 18.7°
From triangle ABC:
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 = 41.3° and ϕ2 = 46.64° 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 along the base as shown.
What is n, the index of refraction of the prism for red light?
