Hippolyte fizeau light
WebbIn 1849, the French physicist Armand Fizeau created a new method to measure the speed of light more accurately using a rotating toothed wheel and a mirror, as illustrated in the picture below. Light coming from the source gets reflected through a rotating toothed wheel. The continuous light will be cut into chunks by teeth on the wheel.

In 1849, Fizeau calculated a value for the speed of light to a better precision than the previous value determined by Ole Rømer in 1676. He used a beam of light reflected from a mirror 8633 meters away. The beam passed through the gaps between the teeth of a rapidly rotating wheel with 720 teeth.
