Speed of light is the speed at which light
and other electromagnetic waves travel
through empty space. Its value is
299,792,458m (186,281miles per second). The
speed of light is the highest speed possible,
according to the theory of relativity, and
its value is independent of the motion of its
source and of the observer.
