Hi,
We know that light changes speed when going from a medium 1 to medium 2 (obviously, they are characterized by different driffactive indexes). Light wavelength doesn't change (same color) during such event.
If medium 1 is less dense than mendium2, the speed of light in medium 1 is faster than in medium 2. The relationship wavelength1 x frequency1 = V1 (speed in medium 1) tell us that speed of light is related to its frequency and wevelength. But if the speed is lower in medium 2, and wavelength 2 x frequency 2 = V2. And remembering that V2< V1, does that means that the wavelength of light when going into medium 2 changes?.
I know, that's wrong and the answer is related to the snell's law but I have not managed to derive a demostration
