how to find which polarization ?? a classical charged particle moving with frequency 'w' in a circular orbit of radius 'a' centerd at the origin in the x-y plane, em radiation. At points (b,0,0) and (0,0,b) where b >> a the em waves are 1. circularly polarised and elliptically polarised respectively 2. circularly polarised and plane polarised respectively 3. plane polarised and circularly polarised respectively 4. plane polarised and elliptically polarised respectively the answer is given to be "plane polarised and circularly polarised respectively" ... Can anyone help how to solve this kind of problems? Thanks in advance !!!
