| Physics Questions: Prism and Refraction? White light is incident onto a 30 degree prism at the 40 degree angle shown in the figure. Violet light emerges perpendicular to the rear face of the prism. The index of refraction of violet light in this glass is 2.0% larger than the index of refraction of red light.
