Instead, he constructed an apparatus consisting of a beam splitter, a rotating toothed wheel and a mirror placed 8 km from the light source. 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.

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. WebQuestion:1) The year was 1848 and 1849, to measure the speed of light, Hippolyte Fizeau spun a wheel with 720 teeth at 13.75" He determined that light that passed through a gap A in the teeth, traveled d = 7500 m, bounced off a mirror and returned to strike the adjacent tooth B of the wheel. a) What speed of light does Fizeau determine?
