Author: w:Albert Abraham Michelson (1852 – 1931) and w:Edward Morley (1838 -1923)

Description: Fig. 6 from "On the Relative Motion of the Earth and the Luminiferous Ether" summarizing Michelson and Morley's results. The upper solid line is the curve for their observations at noon, and the lower solid line is that for their evening observations. Note that the theoretical curves and the observed curves are not plotted at the same scale: the dotted curves, in fact, represent only one-eighth of the theoretical displacements.
