light is a electro magnetic(EM)wave so it has electric nd magnetic particles but y wont it deflect in EM field

Question

as it containg electric and magnetic particles it should deflect in a EM field as when it travels in the EM field the -ve or +ve electric or magnetic particles attract to the -ve or +ve particles of the EM field-this reason is true i suppose,but still its a fact that light does not deflect in a EM field.This is the same with x ray they to r electro magnetic waves but do not deflect in an EM field.

Answer 1

Firstly, you're correct in that it is an EM wave, however there are no such things as electric and magnetic particles within EM waves... Any EM wave is pure energy in waveform.

The positives and negatives referd to in the wave is purely that at one end of the wave cycle, the energy is positive, and then at the other end it's negative... and the cycle continues so the net value of the wave is neutral (just as much positive as negative). That in itself explains why an EM wave does not get deflected by an EM field... the EM field is acting on a neutral wave.

Light is very strange however... it is part of the EM spectrum and as such is a waveform... however, it also acts like particles in certain instances (known as Photons). The reason for this is still a bit of a mystery, but photons are neutral in charge also, so an EM field would not affect these either. (but gravity can, hence light gets deflected around massive objects in space...)
