WebFizeau's rotating wheel This was the first terrestrial method for measuring the velocity of light and was performed in 1849. Light from a source S is focused by a lens L 1 on to the edge of a toothed wheel W which has N teeth. It passes through the gaps between the teeth and on to a second lens L 2, which produces a beam of parallel light. 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 ...
WebApr 25, 2024 · Fizeau and Foucault used slightly differing techniques to reach a similar conclusion. Fizeau used a piece of apparatus that shone a beam of light between the teeth of a rapidly rotating toothed wheel. WebFizeau used optics and carefully a manipulated toothed wheel to investigate the speed of light. A reflective mirror was placed far away from the source of light. Upon reaching the mirror, the light would return back …
