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.

WebSep 23, 2024 · The speed of light measurement was done in 1849. In 1850, Fizeau successfully measured the speed of light in water, found that it was less that the speed in air, and concluded that light must be a wave – if it were a particle, it would have moved more rapidly than in air. 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
