Do all photons have same mass
WebAug 8, 2024 · It's not many physicists but all physicists that define ##m## as strictly the invariant mass. For massive particles it's the rest mass. For photons the mass is 0 and thus never a rest mass, because a photon moves always with the speed ##c## (in the vacuum). Of course photons are no massless particles in a literal sense. Web1 day ago · Medeiros et al. 2024. 61. The iconic image of a supermassive black hole in the Messier 87 (M87) galaxy—described by astronomers as a "fuzzy orange donut"—was a stunning testament to the ...

WebApr 9, 2024 · Mass and Momentum. By now, we know that a photon displays both wave and particle nature. Now, since the photon is a small packet of energy, you can argue that by … WebAnswer (1 of 8): Relativistic mass is really a wrong term. Let’s define mass first. Mass is the measurment of energy an object has while standing still. Mass in itself is nothing just a name associated with the above stated measurement. In quantum physics these days nobody talks about mass ever...
WebApr 9, 2024 · Mass and Momentum. By now, we know that a photon displays both wave and particle nature. Now, since the photon is a small packet of energy, you can argue that by Einstein’s famous equation. E = mc2. something that contains energy must also have some mass. But we already established that photons don’t have mass. WebDec 16, 2010 · Why particle and coresponding antiparticle have the same mass,because in the annihilation process the mass does not conserve. Mass does not conserve but energy does. Mass does not conserve but momentum does. Generally, two photons are created when an electron and positron annihilate. One of the signatures of this …
WebMay 28, 2013 · Although photons don’t have mass, they do have momentum because they are moving (fast!). The higher a light wave’s frequency is, the more momentum it has and the more energy it carries, just ... WebAug 25, 2015 · A photon can still have zero invariant mass ( ), and can still have energy. There’s nothing inconsistent here. All of the photon’s energy is in the term . 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. This may or may not be useful ...
WebDec 14, 2024 · $\begingroup$ @user248881 In the standard model of particle physics all photons are point particles, i,e, have no size. They do not have extent in space, the only difference between a gamma and an infrared photon is in the energy. The E=hν. The Planck constant transforms energy to a number that miraculously is the frequency of the light …

The short answer is "no", but it is a qualified "no" because there are odd ways of interpreting the question which could justify the answer "yes". Light is composed of photons, so we could ask if the photon has mass. The answer is then definitely "no": the photon is a massless particle. personal narrative thesis statement examplesWebJan 3, 2024 · We have a lot of experiments, which clearly show that photons do NOT all travel at the same speed. That phenomenon is called dispersion. There would be no rainbows if all photons traveled at the speed of light!
