WebExpert Answer. plea …. Measuring the Speed of Light: Michelson In 1926. Albert Michelson measured the speed of light with a technique similar to that used by Fizeau. Michelson used an eight-sided mirror rotating at 528 rev/s in place of the toothed wheel, as illustrated in the figure (Figure1). The distance from the rotating mirror to a ... 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…
WebFrench physicist who collaborated with Fizeau in the measurement of the velocity of light using a Fizeau wheel. He invented the Foucault pendulum which demonstrates the rotation of the Earth by changing the plane of its oscillation as the earth rotated underneath it. He also invented the gyroscope.
