How to learn Electromagnetic Fields and Waves at ease

Overview

Most people find it hard to learn the course "Electromagnetic Field and Waves", probably due to its abstraction. Some felt supprised when I said it is my favorite course of the senior year and make it a hobby learning it. I'll introduces the way I learned it.

How I understand complex concept?

A sentence is constructed through words. Similarly, an abstract definition of a complex concept is composed of more basic concepts.

Since it is abstract, I found that it is much easier to visualize it and luckily many physics lover have done it and kindly upload them to YouTube. Once you find that you cannot well explain one concept even if you can't find analogy, don't overthink, just use YouTube as a graphical, visualized Google. Instead of "Google it", you "YouTube it", and make every concept visualized so that you don't need to spend unnecessary time trying to imagine a thing you cannot even be certain about the precondition(, cause you may imagine that too). The main idea is to break things down, in to smallest pieces, totally make it steady in mind(through visualization instead of imagination), and then understand the whole building (abstract/complex concept) by rebuilding it.

You will feel like you are learning a sentence in an unfamiliar language, you look up each unfamiliar word in the dictionary, understanding the meaning of each word, and finally, you read that sentence, and know the concept, so easy.

I watched as many as I could and found the following supper helpful.
