This isn't really a homework question, but I felt it was better suited here than in General Physics. I'm looking for more of a general explanation than anything. I was able to do my homework for this section on my own (mostly), but I feel like I still really have no idea what is actually going on.
So. Electromagnetic radiation. I feel like I'm missing something important to understanding. Basically what I know is this: moving charges can radiate an electric field and a magnetic field. How do we know what direction the fields radiate in? And how do we know in which direction they point? And finally, how can the phenomena be explained?
I tried reading the textbook for answers to these questions, but my course's textbook is a very dry read and was hard to follow. I didn't get much out of it.
Thanks very much in advance for any help.
