What is Speed of Light?

The speed of light is a fundamental physical constant representing how fast light and electromagnetic waves propagate in a vacuum.

Short history of Speed of Light

Since 1983, the meter itself has been defined based on the speed of light, making its value exact by definition rather than measured.
