How can light have no mass

WebAnswer (1 of 20): Classically the energy of a moving object (Kinetic energy) is: KE = \frac{1}{2}mv^2 =\frac{p^2}{2m} Naively one would think that you could plug in m=0 and v=c for a photon and find that it has no energy. We could do the same for momentum, p=mv, and find that photons can't push a... Web8 de set. de 2010 · For light m=0, so E=Pc (energy and momentum are proportional).
