From 1848 to 1849, Hippolyte Fizeau used a toothed wheel apparatus to perform absolute measurements of the speed of light in air.
Subsequent experiments performed by Marie Alfred Cornu from 1872 to 1876 improved the methodology and made more accurate measurements. #Science #knowledge #speedoflight #facts #engineering #viral
