I know accelerated electrons and protons radiate photons, but I would like to know what accelerated free anions and cations radiate or do they radiate photons?
Dear Gebreselema Hk ,
any accelerated charge will emit photons/electro-magnetic radiation irrespective on the mass which is accompanied with the charge; so also anions and cations.
You did not understand my question. I know free accelerated protons emit gamma rays, take note free and accelerated charged particles, not just charged particles. I know accelerated electrons emit x rays ,. ... my question is do free and accelerated an anions and cations emit photons or em?
Ions act magnetically by attracting things with the opposite charge and repelled from things with the same charge. Therefore, a positive ion will be accelerated towards an object charged negatively, and away from a positively charged one. Photons will be emitted during the process.
Dear Gebreselema Hk ,
It all depends on speed and acceleration (or its component). Dark matter does not radiate anything.
Good luck and best regards.
Abiola, thank you. You did not understand the question. I do understand what you are saying which is basic one. I am taking about free ions in vacuum, inside accelerators. They are in vacuum, no particles to attract or repel.
Broadly speaking, bremsstrahlung or braking radiation is any radiation produced due to the deceleration (negative acceleration) of a charged particle, which includes synchrotron radiation (i.e. photon emission by a relativistic particle), cyclotron radiation (i.e. photon emission by a non-relativistic particle)
Electromagnetic theory tells us that accelerated charge emits power with angular distribution. even uniformly moving charges emit power.
For accelerated motion, interaction with field is needed. For uniform motion, we don't need it. Then we say tha free particle can radiate due to charge in motion. More details are needed.
