I'm not really sure how this is a problem, since this is exactly what happens to light in any real medium (it's not even a problem for either or both of them to be greater than c, either). All the cows are is a square wave, really, and square waves are perfectly valid solutions to the wave equation.Rococo wrote:It looks like everyone else is happy, but none of these explanations really do it for me. Qaanol's explains the change in wavefront, but not the change in momentum direction, since in any configuration other than an infinite evenly spaced line his cows have a different group velocity and phase velocity.
This is the ultimate explanation, sure, but you don't need QM to understand and explain refraction. Refraction, reflection, diffraction, and all the rest are properties of all waves, classical and quantum mechanical.Fedda wrote:since I can't get my head around quantum physics which seems to be the proper explanation according to the physicists
