WebWhen light propagates in a medium, its speed is reduced, in the rest frame of the medium, to cm = c⁄nm, where nm is the index of refraction of the medium m. The speed of light in a medium uniformly moving with speed V in the positive x -direction as measured in the lab frame is given directly by the velocity addition formulas. WebIn physics, the principle of relativity is the requirement that the equations describing the laws of physics have the same form in all admissible frames of reference. ... In the Lorentzian case, one can then obtain relativistic interval conservation and the constancy of the speed of light. General principle of relativity
