WebJun 17, 2005 · Fizeau reported the speed of light as 313,000 kilometres per second. Fizeau's method was later refined by Marie Alfred Cornu (1872) and Joseph Perrotin (1900). Leon Foucault improved on Fizeau's method by replacing the cogwheel with a rotating mirror. Foucault's estimate, published in 1862, was 298,000 kilometres per second. 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.
