The problem with EM mnemonic visualizations, none of them reflect or explains reality of EM waves. It is just a memory prop for engineering calculations. You don't have to understand chit of how a black EM box works to come up with usable engineering calculations.
I thought you did a nice job of explaning things. Be careful with how you represent AM, you are showing an envelope, a vectorial combination in a linear system. The carrier wave does not vary in amplitude in reality, even though a scope "combines" the carrier and sidebands, suggest you make a distinction between the carrier and sidebands in your graphics (show a spectrum plot), no need to perpetuate the "misnomer" of AM. I liked when you described spheres within spheres for the EM wave, maybe some sort of attempt at a graphic of that would be nice.
Wonderfully presented!
