==Description==
*This function shows the value of speed of light.
*The speed of light value is <math>29979245800 m s^{-1}</math>.
*The approximate value is approximately <math>3.00×108 \frac{m}{s}</math>.
*It is exact because the unit of length, the meter, is defined from this constant and the international standard for time.
*Speed of light is the distance of light which can travel in a unit of time through a given substance.
*Speed of light in vacuum is denoted by c.
*The speed at which light propagates through transparent materials, such as glass or air, is less than c.
*Similarly, the speed of radio waves in wire cables is slower than c.
*A light year, or the distance light can travel in a year, is over five trillion miles.
*Light from the sun takes about eight minutes to reach the Earth.
*Speed of light is mainly used in Einstein's formula <math>E=mc^2</math>.
