properties.

When does light travel at a speed other than the speed of light?

From another of my postings: "If I remember correctly,
a photon cannot travel slower than the speed of light."

The first nine words in my first statement above are
not mine but were copied verbatim from Rectifier's posting
(except for the misspelled word). If there was an implication
that light can travel at less than the speed of light, it
didn't come from me.

Light travels at different speeds in different media, such as water, glass,
etc.
