Proof photons have mass

WebApr 25, 2015 · formula, the energy of a particle like photon, which shows wave properties as well, is derived from its mass and momentum. Some suggest that photons are indeed mass-less and that photons have energy due to there momentum, but momentum itself is equal to mass times velocity, p = m v .Then how can a body have momentum and not mass? WebSo being an electron or a neutrino, you can say that the relationship between the frequency and the mass is constant. In fact we really have total energy E = Mc^2 = mc^2/sqrt (1 - (v/c)^2) = hF = hc/L; so that F/m = c^2/ (h sqrt (1 - (v/c)^2)), which varies with v the relative speed of the particle.
