1. The problem statement, all variables and given/known data I am trying to understand electromagnetic radiation....(the wave propagation of electric & magnetic fields) and resulting polarization. I just cannot visualize it, and once I think I understand, I see some diagram which challenges my thinking. What is the relationship between electric field, electric lines? Is electric field a scalar or vector? I would think it's a scalar but then polarization makes me think it's a field. Polarization: is x-component = the electric field scalar value and y-component = magnetic field scalar value? What is the relationship between E_theta, E_phi, and E_r and: electric field & magnetic field/lines/values/etc.? 2. Relevant equations n/a 3. The attempt at a solution My attempts just confuse me more. A clear description or visualization would be nice. This question is purely for understanding as there are too many things I don't get. That's what happens when all you're taught is the math behind a concept.
