Light travels through a medium and its velocity is (assuming that the medium has an index refraction greater than 1) consequently slowed. Once the light passes through the medium, though, the velocity at which it travels accelerates back to the rate it had prior to entering the medium.
How did the light gain sufficient energy to accelerate back to its prior velocity?
I was asked this by a family member and am stumped. Any clues?
Thanks!
