I have a light ray traveling through air at 'c' , it then enters some ordinary glass say mu=1.5 , it slows down by mu. --- no problem.
According to the normal equation v = f . lambda , (velocity , frequency , wavelength) ,
'v' has slowed down from 'c' to 'c' / mu therefore the RHS must change
But what changes ?? 1.5 is a LOT.
if glass is a linear medium there seems no reason for 'f' to change , so it would appear that Lambda must .
when the ray exits the glass it changes back so what we see is what went in.
But what about the eye where the ray strikes the retina do we see an altered lambda different from the air ??
