WebAlthough Fizeau's original experiment used a toothed wheel with 720 gaps, this animation uses only 8 gaps. The round-trip distance from the wheel to the flat mirror and back again is 17.3 km, the same as in Fizeau's setup. Can you use Fizeau's experiment to determine the speed of light? WebThe first measurements of the speed of light using completely terrestrial apparatus were published in 1849 by Hippolyte Fizeau (1819–96). Compared to values accepted today, Fizeau's result (about 313,000 kilometres per second) was too high, and less accurate than those obtained by Rømer's method.

"Web1,2,3, the speed of light can be gotten by measuring the displacementΔsfor a given angular speed. In principle, to determine c, a single measurement point is enough, but as we will see later, by measuringΔsas a function of ω, and taking the slope of the linear dependence, it is not necessary to ﬁnd the reference position atω= 0.
