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.

The word was not misspelled. According to dictionary.com, which quotes the
American Heritage Dictionary, "traveling" and "travelling" are both accepted
ways of spelling the word.

Also, I never meant to assert that light can travel at less than the speed
of light. I took modern physics in college and understand the concepts of
relativity, although it's been 20 years; so I may get some terminology wrong
or not be able to explain it as well as I could before. However,
discussions like these are interesting and stimulate thought and a desire to
go back and review the subject.
