When two particles of the same mass are moving in vacuum and only differ in energy (or equivalently momentum) then the particle with higher energy (momentum) should be moving faster, right?
Then how can we claim the speed of light in vacuum is constant? Shouldn't it depend on frequency of the photon? Blue light has more energy than red light and hence would be expected to move faster.
