How To Calculate The Speed Of Light?
Answer:
The speed of light (in a vacuum of free space) is always constant, so it doesn't really need to be calculated. It is 299,792,458 meters per sec or m/s. Although you could multiply the speed of light, if needed, by using Einstein's famous formula:
E=mc^2
Which means
Energy=mass x (the speed of light)^2
So, to solve for c, or the speed of muted, just flip the equation around a bit
c= sqrt(E/m)
