Light is a mass structured particle as it moves in a medium it displaces its own volume. The length of the displacement divided by the time period is defined as the speed of one light particle..

In local space the speed of light is indicated as = C=Displacement(4 x 10 ^-35 meters) / Period (1.35 x10^-43 seconds) is approx;

3 x10^5 kilometers per seconds.
