Calculate the wavelength of a microwave with frequency . Using this, explain why the front window on your microwave oven has small grates on it. b. Calculate the wavelength of radio waves with frequency . Using this, explain why you don’t lose radio reception when a person stands in between your antenna and the broadcast tower. c. Calculate the wavelength of gamma rays with frequency . Using this, explain why gamma rays can deeply penetrate through most objects (and thus are dangerous to humans). d. Estimate an order-of-magnitude frequency for an electromagnetic wave with wavelength equal to your height. What is the classification of this wave on the electromagnetic spectrum? 2. A light wave travels through three transparent materials of equal thickness. a. Rank in order, from largest to smallest, the indices or refraction n1, n2, and n3. Explain your reasoning. b. If a reflection were to occur for the light wave as it was attempting to move from the n2 medium into the n3 medium would it have a phase shift or not? Explain your reasoning. 3.0 ×1010 Hz
