question

how are electromagnetic waves produced by oscillating charges? what is the source of the energy associated with the em waves?

 

 

 

 

 

when a charged particle oscillates with some frequency, so, it produces an oscillating electric field in space which further produces an oscillating magnetic field and thus, in turn,is a source of electric field and this process goes on and hence, an electromagnetic wave propagates in the space. an accelerating charge is the source of electromagnetic waves
