Do all photons have same mass
WebDec 25, 2024 · If you use photons, you don't have to worry about amplitudes, energy is calculated using Photon Energy, and this reference gives you the math. But amplitude is more a wave related concept than any application to particles. If you use waves to describe electromagnetic radiation, the energy is given by this reference, Energy of an … WebAfter all, it has energy and energy is equivalent to mass. Photons are traditionally said to be massless. This is a figure of speech that physicists use to describe something about …
Do all photons have same mass
Did you know?
WebMay 19, 2005 · They must have mass - even if it is a minute amount, otherwise how do they come into interact with gravity. ... Are we saying that all photons are the same size and the energy changes according to the wave length so that there are many more photons communicating energy in a long wave length low frequency radio waves than in a short … WebJan 3, 2024 · Indeed, even though some neutrinos have rest mass as shown by oscillations, we do not have evidence that they all do. But in contrast to low energy neutrinos, low energy photons are easy to observe - longwave radio waves! And they do not show evidence of medium independent, vacuum dispersion which photon rest mass …
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 … 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.
WebAug 9, 2024 · It’s a striking demonstration of the physics immortalized in Einstein’s equation E=mc 2, which revealed that energy and mass are two sides of the same coin. Science … WebAnswer (1 of 5): Photon is nothing but a packet of energy, since there is energy it should have mass or it will be violation of Einstein's equation E=mc^2. So the mass of a photon depends on how much energy it has , since energy is related to the wavelength of light therefore we can say photons ...
WebAfter all, it has energy and energy is equivalent to mass. Photons are traditionally said to be massless. This is a figure of speech that physicists use to describe something about how a photon's particle-like properties are described by the language of special relativity. ... For example, all protons, electrons, and neutrons have the same rest ...
WebSep 2, 2010 · p = 0 (because you have to add two equal and opposite momentum) so: E^2 = (mc^2)^2 --> m = E/c^2. That is: the system of the two photons have mass. Invalid application. Each photon has no rest mass and energy equal to (pc)^2. With 2 photons in opposite directions the energy is (pc)^2 + (-pc)^2 = 2 (pc)^2.

Some particles are their own antiparticles, notably the force carriers like photons, the Z boson, and gluons, which mediate the electromagnetic force, the weak nuclear force, and the strong ... family search church accountWebAug 28, 2004 · Gonzolo said: The short answer is that light doesn't have a rest mass. Only relativistic mass. And it is affected by gravity because gravity curves space-time. Gravity curves spacetime near a ray of light becouse light has momentum and energy, and those gravitate, along with the mass the light doesn't have. Aug 23, 2004. cool kids games online free
