Abstract: Based on the theories of long wavelength photons and minimum frequency in quantum electrodynamics and on the experimental limits of photon mass, the relationship between photon mass and the light velocity has been theoretically explored in recent years.The lowest light velocity υmin is approximately a constant about 10% lower than the limiting velocity c.The vacuum dispersion caused by photon mass, namely the total change of the light velocity from υmin to c, takes place within only a small frequency region nearby the minimum frequency, in other words, only the velocity of the long wavelength photons is dispersed in vacuum.On the other hand, the light velocity with the frequency in common use is always accurately equal to the limiting velocity c without dispersion, therefore Maxwell equations are practically applicable, and the electromagnetic field keeps gauge invariance property so that the photon mass is concealed.A suggestion for how to seek the long wavelength photons is put forward in the paper.
