Unformatted text preview: (1) Calculate the speed (or maximum and minimum speeds if more than one) that light can travel through the minerals. Be sure to include units with your number. (2) Calculate the angle of refraction (in degrees) for each index of refraction, assuming that a the wave normal of a single light ray impinges on a flat surface of the mineral at an angle of incidence (i.e., θ i ) of 50º after passing through air, for which n = 1. (3) Derive the critical angle for each index of refraction for the minerals as the light passes from the mineral into air. 1...
