Phys 375 HW 2 Fall 2010 Due 20 September, 2010 1. Pedrotti 3 , 3 rd edition, problem 2-7 (see Fig. 2-33). 2. Write an expression for the E - and B -fields that constitute a plane harmonic wave traveling in the + z -direction. The wave is linearly polarized with its line of vibration at 45 o to the yz -plane. 3. Prove that to someone looking straight down into a swimming pool, any object in the water will appear to be ¾ of its true depth. 4. Light is incident in air perpendicularly on a sheet of crown glass having an index of refraction of 1.552. Determine the reflectance.

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...
