In 1834, Charles Wheatstone developed a method of using a rapidly rotating mirror to study transient phenomena, and applied this method to measure the velocity of electricity in a wire and the duration of an electric spark. He communicated to François Arago the idea that his method could be adapted to a study of the speed of light. The early-to-mid 1800s were a period of intense debate on the particle-versus-wave nature of li… WebThe Fizeau Wheel is used in Fizeau experiment to calculate the light speed. This instrument comprises of a rotating toothed wheel. Light beam is passing through the wheel. A distant mirror is used to reflect the light beam. The reflected beam is going back to the wheel.

The basic procedure is to … Fizeau was born in Paris to Louis and Beatrice Fizeau. He married into the de Jussieu botanical family. His earliest work was concerned with improvements in photographic processes. Following suggestions by François Arago, Léon Foucault and Fizeau collaborated in a series of investigations on the interference of light and heat. In 1848, he predicted the redshifting of electromagnetic waves. In 1849, Fizeau calculated a value for the speed of light to a better precision than the previous v… WebFizeau's experiment was later modified by French physicist Jean Léon Foucault (1819-1868), who replaced the toothed wheel with a rotating mirror. With this new arrangement … greenlight amazingly fast
