Fizeau's toothed wheel experiment

In 1834, Charles Wheatstone developed a method of using a rapidly rotating mirror to study transient phenomena, and applied this method to measure the velocity of electricity in a wire and the duration of an electric spark. He communicated to François Arago the idea that his method could be adapted to a study of the speed of light.

WebFizeau The 19th century brought a number of quite accurate measurements of c. The 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. WebNov 27, 2014 · In short, in Fizeau’s apparatus, a beam of light was shone between the teeth of a rapidly rotating toothed wheel, so the “lantern” was constantly being covered and uncovered. Fizeau had a mirror, reflecting the beam back, where it passed a second time between the teeth of the wheel.
