Unformatted text preview: Problem Set 1 Physics 2216 : Due Thursday, 01/26/2012 1. In this problem, we will investigate the Michelson-Morley experiment in a bit more depth. Our apparatus is as shown below, two mirrors at 90 ◦ to one another, one mirror axis along the direction of motion and the other mirror perpendicular to the direction of motion. The mirrors are a distance L from the source / detector (in the real experiment, this was a half-silvered mirror at 45 ◦ acting as a beam splitter). Let’s start by working under Michelson’s and Morley’s original assumptions which were that a) the earth is moving with a velocity V relative to the luminiferous ether, and b) that the speed of light is not absolute in all reference frames, but is always c relative to the ether only . a) Calculate the expected amount of time, t 1 , that it would take to travel along the first path : from the emitter, to mirror A, and back to the emitter. Again, remember that we are calculating what Michelson and Morley would have assumed, given there...
