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. WebAug 22, 2024 · Fizeau’s method to determine speed of light: Apparatus: The light from the source S was first allowed to fall on a partially silvered glass plate G kept at an angle of 45° to the incident light from the source.
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. WebSep 23, 2024 · September 23, 2024.
