WebPhoton momentum is indeed small. Even if we have huge numbers of them, the total momentum they carry is small. An electron with the same momentum has a 1460 m/s … WebMomentum of Photon For a photon, the relativistic momentum expression approaches zero over zero, so it can't be used directly to determine the momentum of a zero rest mass particle. But the general energy expression can be put in the form and by setting rest mass equal to zero and applying the Planck relationship, we get the momentum expression:

WebThe magnitude of momentum of a photon with energy E = hf is p = E/c = hf/c = h/λ. When an electromagnetic wave interacts with a small particle, it can exchange energy and momentum with the particle. Momentum is a vector, momentum is conserved in interactions, and when two particles interact, the rate of change of one particle's momentum is ... WebEach photon has momentum p (= h ν/c), energy, E (=hν) and speed c, the speed of light. Photons are electrically neutral, and are not deflected by electric and magnetic fields. Photons can be destroyed or created when radiation is absorbed or emitted, respectively. The total momentum and total energy are conserved in a photon-particle collision. cheaters farmville 2
