Hello. I started studying wave optics a while back and here is my first question From what i understand, electric field is a region where charged particles feel the coulomb forces. And light is basically time varying magnetic and electric waves being propagated in some medium or vacuum. What i don't understand is how can something like an electric field be propagated in the first place? How can it move. Isnt it supposed to be a mathematical description of Force? Or is it something like introducing electric field at points in space with varying magnitude? I hope i have made my question as clear as possible. Thanks.
