Unlike that related Trouton-Noble experiment, this experiment utilized a device consisting of two perpendicular arms with a beam-splitter located at the intersection, designed to produce different fringe interference patterns dependent on the path of light.
One follow-up to this experiment concerned the realignment of a parallel-plate capacitor at the Earth's surface. Unlike that related Trouton-Noble experiment, this experiment utilized a device consisting of two perpendicular arms with a beam-splitter located at the intersection, designed to produce different fringe interference patterns dependent on the path of light. Its results suggested that the propagation of light does not change with direction, shown with the use of an interferometer. For 10 points, name this doubly-eponymous 1887 experiment that helped disprove the idea of the luminiferous ether.
