Web27 de set. de 2011 · If you choose to use the one called relativistic mass, E=mc 2 holds, and light has a non-zero value of m so that it can have energy. The more common choice, and the one that's used when saying light is massless, is the invariant mass. If you use the invariant mass, the proper equation is E 2 =m 2 c 4 + (pc) 2, where m=0 for light, and p … WebBasically, stating in a very simplistic way, the m in p=mv is not the rest mass of the photon (which is 0) but the relativistic mass (which is not 0) so the photon has momentum. You can see that a massless particle traveling at c has an ill-defined momentum, according to this formula (zero over zero). But if you take the limit of mass going to ...
