WebFizeau's experiment was later modified by French physicist Jean Léon Foucault (1819-1868), who replaced the toothed wheel with a rotating mirror. With this new arrangement Foucault determined the speed of … WebThe French scientist Fizeau used a rapidly rotating toothed wheel to chop a light beam and measured the time for the beam to return from a distant mirror as the time it took the wheel to rotate su ciently for a tooth to block the returning beam. The value he reported in 1849 was c = 3:15 108 m/s. Wheatstone, Foucault, and Michelson ...
