How did fizeau measure the speed of light
The Fizeau experiment was carried out by Hippolyte Fizeau in 1851 to measure the relative speeds of light in moving water. Fizeau used a special interferometer arrangement to measure the effect of movement of a medium upon the speed of light.

Incoming light is split into two beams by a beam splitter (BS) and passed through two columns of water flowing in opposite directions. … Ver mais Albert A. Michelson and Edward W. Morley (1886) repeated Fizeau's experiment with improved accuracy, addressing several concerns with Fizeau's original experiment: (1) … Ver mais Although Fresnel's hypothesis was empirically successful in explaining Fizeau's results, many experts in the field, including Fizeau … Ver mais Einstein showed how Lorentz's equations could be derived as the logical outcome of a set of two simple starting postulates. In addition Einstein … Ver mais Assume that water flows in the pipes with speed v. According to the non-relativistic theory of the luminiferous aether, the speed of light … Ver mais An indirect confirmation of Fresnel's dragging coefficient was provided by Martin Hoek (1868). His apparatus was similar to Fizeau's, though in … Ver mais In 1892, Hendrik Lorentz proposed a modification of Fresnel's model, in which the aether is completely stationary.
