Hi, there.
I don't understand how the light travel in the medium which has the index of refaction below one
from the following topic:
http://en.wikipedia.org/wiki/Total_external_reflection
“For X-rays, however, all materials have indices of refraction slightly below 1. ”
I did some calculations before, for same light pulse, in certain materials, the index of fraction do have a value smaller than 1.
Does this mean the light is traveling faster than c?
