If the index of refraction of glass for red light is 1.45, what is the speed of a light, the speed of a photon, in the glass?
The same as the speed it would have in a vacuum, that is the same as "c"
Faster than the speed it would have in a vacuum by the factor 1.45
Dependent on the energy or power in the light
Slower than the speed in vacuum by the factor 1/1.45
