What will the angle of refraction be for a beam of light moving from air into a prism if the angle of incidence is 80° and the prism's index of refraction is 1.75?
Snell's law also applies to situations where the beam of light is moving from the prism into air. In this case, n1 is the index of refraction of the prism and n2 is the index of refraction of air, or 1.00. What is the angle of refraction for a beam of light moving from a prism to air if the angle of incidence is 30° and the prism's index of refraction is 1.6?
