WebApr 27, 2010 · However, even for a photon the following definition of energy applies: E² = m²c^4 + c² ( p. p) As does the following definition of the four-momentum: P = (E/c, p) Since m=0, combining those two gives the four-momentum of a photon as: ( p , p) or equivalently for a photon traveling in the x direction: (E/c,E/c,0,0) Apr 18, 2009 #3 protonchain 97 0 WebEinstein's E = mc^2 formula is actually a special case of the special relativity formula E^2 = p^2c^2 + m^2c^4, where p is momentum, m is rest mass, E is energy, and c is the speed of light. If you substitute 0 for m (because a photon is massless), and E = hv (the formula for the energy of a photon), you get hv=pc. the warehouse mobile
