I am actually no physicist , but a computer scientist. Probably you will want to personally murder me for asking such a dumb question , but I have no knowledge of physics and I am asking out of curiosity.
As far as I understand , photons die out when they interact with other matter. Thus , when a photon interacts with an electron of a lower energy level , the latter absorbs the photon and charges up and after a while discharges (emits the energy difference). And my question is :
Can a magnetic (or other field) stop light in mid air ? For example , assume that a flashlight it pointed towards a wall , and there is a field in between the two latter objects. Is there a way that such a field may stop the light before it ever interacts with the wall ? In other words, imagine that you are witnessing the light being projected from the flashlight and then just disappearing mid distance and never reaching the wall. And again , please understand that I am a complete newbie in physics and I am asking just out of pure interest.
