Fizeau toothed wheel
WebFizeau's rotating wheel This was the first terrestrial method for measuring the velocity of light and was performed in 1849. Light from a source S is focused by a lens L 1 on to the edge of a toothed wheel W which has N teeth. It passes through the gaps between the teeth and on to a second lens L 2, which produces a beam of parallel light. WebApr 25, 2024 · Fizeau and Foucault used slightly differing techniques to reach a similar conclusion. Fizeau used a piece of apparatus that shone a beam of light between the teeth of a rapidly rotating toothed wheel.
