We know that light travels at the same speed in vacuum regardless of the observer.And light also travels at a speed of c/n in the medium.My question is since c/n is the limit speed in medium,then do we have the similar Lorentz transformation in the medium which just replace c with c/n?(adsbygoogle = window.adsbygoogle || []).push({});

For example, suppose space is filled with medium.And the observer is in S-frame in the medium. A light is travelling in S'-frame which is also in the medium and is moving at the speed of u respect to S.Then what's the speed of light that the observer measures in S? c/n?
