if so, what is that and how is resting mass different than just mass?
Ok, thank you. I was just confused I had because I had always been told they had no mass at all (because they don't interact with the Higgs fields right?) so it didn't make sense to me as to why they would have resting massOrodruin said:The photon mass is zero and it is not very correct to talk about a photon rest mass as they cannot be at rest. For massive particles, rest mass is what physicists normally refer to when they say "mass". The term "relativistic mass" is not used much and you will have a hard time finding a physicist who refers to it as just "mass".
Heh,... and I really wish we would always say "invariant mass" instead of "rest mass".jtbell said:Please, in English, we say "rest mass", not "resting mass."
A photon is a type of elementary particle that carries the electromagnetic force. According to the theory of relativity, it has no rest mass but does have energy and momentum.
A photon is not considered a matter or antimatter particle because it has no rest mass and therefore does not interact with the Higgs field, which is responsible for giving particles their mass.
No, a photon cannot have a measurable mass because it travels at the speed of light and therefore has no rest mass. Its energy and momentum are attributed to its frequency and wavelength.
Einstein's famous equation, E=mc², states that mass and energy are interchangeable. For particles with no rest mass, such as photons, their energy is equal to their mass multiplied by the speed of light squared.
Yes, although a photon has no rest mass, it does have energy and momentum, which means it can be affected by gravity. This is seen in phenomena such as gravitational lensing, where the path of light is bent by the gravitational pull of a massive object.
