WebJul 29, 2024 · Once you leave that medium and go back into a vacuum again, that light goes back to moving at the speed of light. And to the best of our knowledge and … The speed at which light waves propagate in vacuum is independent both of the motion of the wave source and of the inertial frame of reference of the observer. This invariance of the speed of light was postulated by Einstein in 1905, after being motivated by Maxwell's theory of electromagnetism and the lack of evidence for the luminiferous aether; it has since been consistently confirmed …
