Re: Not understanding some parts of wave refraction

I think we both understand that light travels at a velocity which is dependent on the medium through which it is travelling. You seem to want to continue to argue about that, and to tell you the truth I can't see much difference between that, and the kind of debate going on over and over in this newsgroup.

This isn't the first time I've failed to communicate, and I'm sure it won't be the last.

The sole point I was trying to make is that the letter c is just about universally used, as far as I can tell, to mean the velocity of light in a vacuum. That symbol is not generally used to mean the speed of light in any other medium.
