Two photons are moving in opposite directions each with a velocity of light (c). Then their relative velocity is:
Two photons are moving in opposite directions each with a velocity of light (c). Then their relative velocity is c.
The Special Theory of Relativity:
According to relativity, the speed of light is a universal constant. Any velocity added or subtracted to the speed of light yields velocity of light.
The special theory of relativity (1905) is based on the following two postulates:
- Laws of physics have the same form in all inertial reference frames moving with a constant velocity with respect to another.
- The speed of light has the same value for all observers in a different inertial frame of reference.
