WebFizeau’sMethod 3. Foucault’s Method 4. Bradley’s Method 5. Michelson Morley Method Michelson Morley Method In 1926, Albert Michelson measured the speed of light with a technique similar to that used by Fizeau’s. Michelson used an eight-sided mirror rotating at 528 rev/s in place of the toothed wheel, as illustrated in the figure below . 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 ...
