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 surprised when I said it was my favorite course of the senior year, and I even made it a way of my relaxation. I'll introduce the method I learned.
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 lovers have done it and kindly uploaded them to YouTube. Once you find that you cannot explain one concept and cannot even find an 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 something you cannot even be certain about the precondition (cause it may also be your imagination). The main idea is to break things down into the 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 helpful.
