Subject: Re: You use different lenses underwater because the speed of light is different



We need to define our terms: the word "light" here is being used
rather loosely. I define "speed of light" as it's speed in a vaccuum.
i define "light" as a single photon.

When you read that the "speed" of light is slowed in a medium, it means
that the propogation of it is delayed. However, the speed of one
photon, as it leaves one atom and goes to another IS NOT SLOWED. This
is the source of much confusion, even among scientists! If I'm wrong,
let me know, always want to know. The "delay" is referring to the
propogation of the wavefront, which is diff. from a single photon. The
speed of light does not change, not ever, or Einstein was wrong. The
"delay" is caused by atoms getting in the way of the wavefront,
absorbing it, re-emitting it, etc. This cocept is never explained in
the popular press, or the scientific press, either!
