http://sasuke.econ.hc.keio.ac.jp/~ken/physics-faq/photon_mass.html WebThe photon is a particle that exists only moving with speed c. In accordance with the second postulate of Einstein’s special relativity the photon moves with c relative to all inertial observers in relative motion. Existing only in a state of motion relativists consider that the rest mass of a photon is equal to zero.

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: Webproton, stable subatomic particle that has a positive charge equal in magnitude to a unit of electron charge and a rest mass of 1.67262 × 10−27 kg, which is 1,836 times the mass of an electron. Protons, together with electrically neutral particles called neutrons, make up all atomic nuclei except for the hydrogen nucleus (which consists of a single proton). Every …
