Fizeau experiment - Wikipedia

In 1848−49, Hippolyte Fizeau used a toothed wheel apparatus to perform an absolute measurement of the speed of light in air. Subsequent experiments performed by Marie Alfred Cornu in 1872–76 improved the methodology and made a more accurate measurement. WebThis effect was first observed by Fizeau in 1851.
