Velocity of Light in Vacuum

c

Definition

The velocity of light in vacuum is the speed at which light travels in a vacuum, approximately 299,792,458 meters per second. It is a fundamental physical constant and the maximum speed at which all energy, matter, and information can travel in the universe.

History/Origin

The velocity of light was first measured by Ole Rømer in 1676, but its exact value was refined over centuries. In 1983, the meter was redefined in terms of the speed of light, making it a fundamental constant of nature with an exact value.

Current Use

The velocity of light is used in physics, astronomy, telecommunications, and various scientific applications. It is fundamental to Einstein's theory of relativity and is used in GPS systems, fiber optic communications, and astronomical calculations.
