Description
- This function shows the value of speed of light.
- The speed of light value is Failed to parse (MathML with SVG or PNG fallback (recommended for modern browsers and accessibility tools): Invalid response ("Math extension cannot connect to Restbase.") from server "https://wikimedia.org/api/rest_v1/":): {\displaystyle 29979245800 m s^{-1}} .
- The approximate value is approximately Failed to parse (MathML with SVG or PNG fallback (recommended for modern browsers and accessibility tools): Invalid response ("Math extension cannot connect to Restbase.") from server "https://wikimedia.org/api/rest_v1/":): {\displaystyle 3.00×108 \frac {m}{s}} .
- 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 Failed to parse (MathML with SVG or PNG fallback (recommended for modern browsers and accessibility tools): Invalid response ("Math extension cannot connect to Restbase.") from server "https://wikimedia.org/api/rest_v1/":): {\displaystyle E=mc^2} .
