Air (n1 = 1.0) surrounds a solid glass cube (n2 = 1.5) withedge length a = 7.0 cm. An incoming ray of light strikes thecube at the midpoint of face #1 (the front face). The refractedray strikes the midpoint of the edge that is shared by face #2(the top face) and face #6 (the back face). What angle ofincidence ?1 did the ray of light make with face #1? For thelimits check, investigate what happens to ?1 if the glass cube’sindex of refraction approaches that of air (n2 ? n1).
