Speed of Light


The speed of light (in a vacuum) is a physical constant.

Information cannot travel faster.

It is usually denoted $c$, and its value is given as:

$c = 299 \, 792 \, 458 \text { m s}^{-1}$


The metre is in fact defined in terms of the speed of light and the definition of the second.

Its $\LaTeX$ code is c .
