Fizeau’s experiment showed that the speed of light is affected by the motion of the medium in which
it is propagated at normal incidence. This effect is regarded as a consequence of relativistic addition of velocities, which gives Fresnel’s law. A correction is proposed to Fresnel’s law for the speed of light in a moving medium, on the basis of addition of velocities in classical mechanics, to give a non-relativistic explanation of result of the experiment.
