Nothing to do with the argument, but I believe there is an exception
that comes to exceeding the speed of light, and that is when the wave is
slowed in a medium to a speed less than c.

Hi Richard,

You are right, of course. Cecil's one-size-fits-all answers always
fail abruptly.

What you are describing is associated with Cerenkov radiation (not the
radiation, but the stimulus of the radiation, which is a charged
particle traveling faster than the speed of light for the medium
within which it travels).
