WebFeb 20, 2024 · There is a relationship between photon momentum p and photon energy E that is consistent with the relation given previously for the relativistic total energy of a particle as. (29.4.2) E 2 = ( p c) 2 + ( m c 2) 2. We know m is zero for a photon, but p is not, so that Equation 29.4.2 becomes. p = E c (for photons).

From a theoretical perspective, if the rest mass of the photon was found to be nonzero, classical electromagnetism and QED … WebAug 25, 2015 · A photon can still have zero invariant mass ([itex]m_0[/itex]), and can still have energy. There’s nothing inconsistent here. All of the photon’s energy is in the term [itex]pc[/itex]. Some people would say that this is the photon’s “inertial mass”, since it is similar to the inertia that one feels when trying to stop a moving mass.

WebNov 2, 2024 · Photons have no inertial mass and no relativistic mass. Experiments have demonstrated that photons do have momentum, though. Special relativity explains this effect theoretically. Gravity affects photons in a way similar to how it affects matter. The question of how light travels through space is one of the perennial mysteries … WebOct 15, 2024 · This answer specifically states that a photon, having stress-energy, contributes to the stress-energy tensor, thus has gravitational mass, and this fact together with the fact that photons do have their own gravitational effects means that inertial mass=gravitational mass for the photon. Though, many on this site identify inertia with …

WebIn short, even though photons have no mass, they still have momentum proportional to their energy, given by the formula p=E/c. Because photons have no mass, all of the momentum of a photon actually comes from its … WebSummary. The energy has a mass and it can be massless also. The energy that a particle possesses is due to its mass and momentum. For the massless particle, the energy that it gains is from the momentum and the speed of such particles which are massless moves with a speed equal to light particles. ← Previous Post.
