Suppose you are using total internal reflection to make an efficient corner reflector, such as the one shown in the figure below. If there is air outside and the incident angle 8, is 54.6°, what must be the minimum index of refraction of the material from which the reflector is made? 1.23 X Can you write Snell's law for the cases where the angle of incidence in the material is 8₁ and ₂, respectively? How are 0, and 8₂ related? Which case of total internal reflection is critical to the determination of the index of refraction of the material? How is the critical angle for the material related to the angle of incidence in the material?
