I'm asking this question in the quantum physics part because I'd like a quantum related answer.
When a charge is accelerated, it will radiate photons. In my belief, it must radiate continuously as long as it's accelerated.
Maybe I'm getting a wrong picture. Imagine an electron moving through empty space between 2 opposite charged plates (capacitor). It will be accelerated toward one plate. But since I had not took any serious quantum course, I don't know if the E field between the plate is really continuous or made of EM waves or whatever I can imagine. Thus I'm not 100% sure if the electron will be accelerated at any moment, or by quanta. If it is accelerated at any moment, it should emit continuously I believe... Producing infinitely many photons, which doesn't occur obviously. Therefore I'm missing someting.
Another question: When a charge is accelerated very shortly, its speed will increase, it will emit at least 1 photon... but in what direction? Is that random? Or opposite to the direction motion of the accelerated particle, so that the speed of the charge gets lower than the speed it had right after the acceleration? And if so, is the speed of the particle the same as it was before the acceleration? If so, it would mean that the energy required to accelerate the electron has been 100% converted into a single photon and that the electron's motion remains unchanged... But with Heisenberg's uncertainty principle, I guess I'm far from guessing things right.
I'd appreciate any comment or any link/name of textbooks on the subjet.
Thanks a lot.
