A beam of light is incident on a prism of a certain glass at an angle of ? =35.0°. If the index of refraction of the glass for green light is 1.40, find (a) the angle of refraction at the air-glass interface, (b) the angle of incidence at the glass-air interface, and (c) the angle of refraction when the green light exits the prism. (d) what is the amount by which the green light is displaced vertically if the base is 10 cms?
