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 . WebConsider the double Fizeau toothed wheel of Wood, which is shown schematically in plan view in Fig. 1. Here WI and WI are the two toothed wheels, mounted on the axle A. The tops of the wheels, which are presented to the observer, are in motion toward the right. with 1 l~. W. Wood, Physical Optics (Macmillan, second edition, 19i1), p 690.

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. boots domestic violenceWebThe 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.
