Two photons each with a speed c are approaching to each other. what is their relative velocity with respect to each other?


Question asked by: zahidph

Not sure, but I think that they would each measure the other photon as also travelling at the speed of light because the speed of light is an absolute, unlike something like the speed of a car etc whereby you simply add or subtract velocities.
