Speed of Light

Written by Jerry Ratzlaff on . Posted in Classical Mechanics

Speed of light, abbreviated as c, in a vacuum, travels at a speed of exactly 299,792,458 meters per second, or about 300,000 kilometers per second, a speed which remains constant irrespective of the speed of the source of the light or of the observer.


Speed of Light formula

\(\large{ c =  \lambda \; f     }\)  


\(\large{ c }\) = speed of light

\(\large{ f }\) = frequency

\(\large{ \lambda }\)  (Greek symbol \lambda) = wavelength
