On the relative motion of the earth and the luminiferous ether with edward w. It compared the speed of light in perpendicular directions in an attempt to detect the relative. The michelson morley experiment was an attempt to detect the existence of the luminiferous aether, a supposed medium permeating space that was thought to be the carrier of light waves. Michelsonmorley experiment, an attempt to detect the velocity of the earth with respect to the hypothetical luminiferous ether, a medium in space proposed to carry light waves. This movie simulates the setup used in the michelsonmorley experiment, including the nonexistent aether wind they were trying to detect. Naturally, something that allows solid bodies to pass through it freely is a little hard to get a grip on. Josiah willard gibbs preface to elementary principles in statistical mechanics. Elementary arguments are put forward to precisely derive the most general allowable form of the directional dependence of the oneway velocity of light. Therefore it was assumed that there is an ether which propagates light waves. Morley, constructed a new interferometer with multiple mirrors and a pathlength about 10 times longer. Detecting the aether wind was the next challenge michelson set himself after his triumph in measuring the speed of light so accurately.

Robert andrews millikan on the elementary electrical charge and the avogadro constant. Using an interferometer floating on a pool of mercury, they tried to determine the existence of an ether wind by observing interference patterns between two light beams. Naturally, something that allows solid bodies to pass through it. Morley henry augustus rowland screw the highest aim of the physicist. The experiment was performed between april and july 1887 by albert a. The basic idea is to detect the time difference between light going upstream then downstream and light going across shore and back. The experiment of michelson and morley arises at the end of the 19th century, where the diverse images of the ether that the scientists constructed were managing to justify different physical phenomena, since it is the case of the hypothesis of partial dragging which was explaining the stellar aberration and the electromagnetic ether as support of the.
