WebThe speed of light in vacuum is denoted as c and its value is, c = 3×108 ms-1. It is a very high value. Several attempts were made by scientists to determine the speed of light. The earliest attempt was made by a French scientist Hippolyte Fizeau (1819– 1896). That paved way for the other scientists too to determine the speed of light.

Finally I broaden the subject and try to provide some reasons why Fizeau started to measure the speed of light originally (section 9). This is done by pointing out some links to a further experiment. 2. how do i go gray after dying hair brownThe Fizeau experiment was carried out by Hippolyte Fizeau in 1851 to measure the relative speeds of light in moving water. Fizeau used a special interferometer arrangement to measure the effect of movement of a medium upon the speed of light.
