A beam of red light is incident on an equilateral prism as shown in Fig. 22.31.

(a) If the index of refraction of red light of the prism is 1.400, at what angle θ does the beam emerge from the other face of the prism?
(b) Suppose the incident beam were white light. What would be the angular separation of the red and blue components in the emergent beam if the index of refraction of blue light were 1.403?
(c) What would it be if the index of refraction of blue light were 1.405?
