Unformatted text preview: 5. Show analytically that a beam of light entering a planar transparent plate, as in the figure, emerges parallel to its initial direction. Consider the case where the plate has a side length t , and the laser beam has an angle of incidence , and angle of refraction at the first interface of . Find an expression for the lateral displacement of the exiting beam relative to the incident beam, s , in terms of t and trigonometric functions of and . Use Snells law and some geometrical thinking. t s Glass plate...
