At the center of its setup was a semi-silvered mirror at a 45 degree angle, with two equidistant mirrors placed horizontally and vertically.
A variation of this experiment that added heavy lead blocks on one side to create asymmetry was performed by Gustaf Hammar. An attempt to reproduce it on a larger scale was conducted at by Dayton Miller, who had worked on trying to reevaluate the negligible fringe shift value that was observed in it. At the center of its setup was a semi-silvered mirror at a 45 degree angle, with two equidistant mirrors placed horizontally and vertically. For 10 points, what 1887 experiment used an interferometer to disprove the existence of the luminiferous aether?
