Why do photons have momentum but no mass? - Quora

WebA photon is a moving particle which does not really stop. It has the same speed as the that of light. Since it does not stop, it may not have a rest mass, but does that means it has no … WebJan 12, 2015 · Note that because a photon has no mass, its kinetic energy equals its total energy. The energy of light allows it to create a gravitational field according to General Relativity. As should be obvious, energy is just one of many properties that photons carry. Photons are much more than "pure energy". tenis wilson branco

WebAs far as we know, photons are massless. If they do have a mass it must be less than 10-54kg, less than a trillionth that of an electron. Most of the misconceptions your teacher has comes from various inappropriate versions of energy, mass, and momentum. This isn't the case, gravity affects the paths things travel on, including the paths of light. tenis wilson masculinoWebJun 13, 2013 · The M in this case is the rest mass divided by the Lorentz factor (= 0 for anything going at the speed of light), so for photons M = 0/0, when you try to use the equation. it would mean that our photon has a mass of 1.000692285594456e-8 Kg (if we assume that the speed of light is 299,792,458 m/s). tenis wilanow
