Answer 1

Answer:

please Mark me as a brainlist answer.

Explanation:

Speed of light does not change, it has to travel more in a mediumthan in vacuum, When light is passing through a medium, the electrons in the medium absorbs the energy from the light and gets excited and releases them back. ... The only reason why a photon can travel at light speeds is because it is mass less.
