Light only travels in a vacuum and travels faster when the sound source is moving. According to the special theory of relativity, c is the upper limit for the speed at which conventional matter, energy or any signal carrying. Light is an electromagnetic wave that does not require a medium for transmission.

In a vacuum, em waves travel at a constant speed, and they travel very fast—about 300,000 kilometers (186,000 mi) per second. This is equal to the speed of light in a vacuum divided by the refractive index of the material it is traveling through (1 for vacuum, 1.003 for air, 1.33 for water, etc). Light appears slowed in matter because the waves bounce off eachother causing interference, which has the net effect of making the light appear to move more slowly. Show the speed of light in vacuum is the maximum.
