Are you proposing that a photon cannot travel slower than the speed of
light in a vacuum, or it cannot travel slower than the speed of light
in water or the speed of light through glass or air? Please reference
which speed of light a photon cannot travel slower than. Assuming your
answer is the universal constrant "c", then my question is, knowing
that light travels faster through a vacuum than it does through water,
is the light travelling through water still "photons" or is that
impossible because they are travelling too slow? What are they then?
Please advise. Thanks.


My gawd that is a LOT of text for a simple point! Do you have any
schooling at all? But then, there is a "velocity factor" and this is
the property of the media "it" travels ... And, the velocity of light,
or RF, though a media, is differing, yes ...And, I have nothing to add
on photons speed thought any material ... indeed ... photons and waves
are very much in debate here ... but then, if you are/were awake, you
already "know" that ...

Anyway, the short answer, think "velocity factor" and yes, "they" do
travel MUCH slower than the speed of light ...

And, actually, your question seems one posed by a complete idiot ... but
then, you DON'T REALIZE THAT, DO YOU?

Anyway, good luck in all your pursuits ... ;-)

When traveling through a medium other than a vacuum
they do travel MUCH slower than the speed of light
*in a vacuum* but they travel at exactly the speed
of light *in the medium*, i.e. the photons don't
know that they have slowed down. :-)
