It's derives fromceleritās - Latin for speed. It can also be considered as standing for constant. Usually written in lower case
The quantity designated by the letter "c" is the speed of light
C = Speed of light, C2 =speed of light squared
The speed of light is equal to 1 unit of c, where c is the speed of light in a vacuum, approximately 299,792 kilometers per second.
The scientific name for the speed of light is "speed of light" or "c." In equations, it is often represented by the letter "c," which stands for "celeritas," the Latin word for speed.
According to Wikipedia, the symbol c, for the speed of light, originates from the Latin word celeritās, for speed.
The equation used to determine the speed of light in a given material is v = c / n, where v is the speed of light in the material, c is the speed of light in a vacuum, and n is the refractive index of the material.
Electromagnetic energy travels at c, the speed of light. The speed of light, c, is 299,729,458m/s
Energy equals mass times the speed of light squared. C is the speed of light
Normally its a lowercase c, as in E=m(c)2. Energy=mass times the speed of light squared.
c always equals the speed of light
wavelength = c/frequency of light where c is the speed of light.
c that's the speed of light
