6D40.u1 - Michelson-Morley Search for Aether
To demonstrate Michelson-Morley's experimental search for aether and how it didn't work.
Place the optical interferometer, laser, an image plate with attached piece of paper, and a camera onto a board that is placed on top of a turntable. The turntable should reside under the optical interferometer. Once the pattern is found and the assembly is aligned, use felt strips to block of the reflected beams and allow for the apparatus to be rotated 180 degrees.
With the camera showing the image to the class and the laser turned on, rotate the assembly around and observe that the pattern does not move at all. This is the result that Michelson & Morley observed proving that Aether does not exist.
