Accelerated charges
 
My days in high school are almost at an end and I don't want to run to my teachers with this question.
So can someone please explain this to me: why an accelerated charge emits photons and loses energy?
Links and references are also welcome. Thanks in advance.

This radiation is present in classical electrodynamics also. Google for "Larmor formula".

Ok...that went way over my head! I haven't learnt electrodynamics yet!! So could you kindly explain what is happening without equations?

thanx a lot!!! that gave me explanations to a lot of "untold stories". i admit that i need to pursue a little more of this to understand the full explanation with maths... but still, something, is much much better than nothing.
:D

one more question... will a moving charge be influenced by the field it creates?
