Fizeau's determination of the speed of light
WebScientists had already determined that light traveled at varying speeds through different mediums, but until Fizeau’s experiments, they believed that if a medium was moving, the speed of light would be obtained by … WebArmand-Hippolyte-Louis Fizeau, (born Sept. 23, 1819, Paris, France—died Sept. 18, 1896, Nanteuil-le-Haudouin), French physicist noted for his experimental determination of the speed of light. Fizeau worked with …

WebFizeau used optics and carefully a manipulated toothed wheel to investigate the speed of light. A reflective mirror was placed far away from the source of light. Upon reaching the mirror, the light would return back to the … WebSpeed of light (c) = 4nNd Fizeau's values were: 2d = 17.26 km, N = 720, n = 12.6 revs per second, giving a value of 3.13 x 10 8 ms -1 for the speed of light. The light must be monochromatic to give a parallel beam and the teeth on the wheel should be blackened to stop unwanted reflections. Foucault's rotating mirror
