The drawing illustrates the dispersion of light by a prism. The prism is made from a certain type of glass, and has a cross section shaped like an equilateral triangle. The indices of refraction for the red and violet light in this type of glass are 1.630 and 1.654, respectively. The angle of incidence for both the red and violet light is 60.0°. Find the angles of refraction at which the
(a) red and
(b) violet rays emerge into the air from the prism.
