Modern Physics: Momentum of Photon
Modern Physics: Momentum of Photon Topics The momentum of a Photon The momentum of a light beam. The momentum of a Photon Photons have momentum even though they don't have mass We came up with an equation that describes the total energy of the particle squared is equal to the rest mass energy squared plus the momentum times the speed of light whole squared. Click on the image for a better view. This equation did give us the momentum of any kind of particle which is moving at any velocity So how does that deal with or works for a photon? Well, a photon has no mass, when we are dealing with photon we can say that mass 'm(ph)' = 0 and of course them traditional sense of momentum we know that momentum is equal to the mass times velocity i.e. p = mv. So we know that if the particle does not have momentum but that is actually not the because with the given equation if we assume that rest mass (m0) of the particle is zero. m0 = 0 then Click on th...
