QED is about Photons, not EM waves.

From "QED", by Feynman: "So now, I present to you the three basic
actions,
from which all the phenomena of light (EM waves) and electrons arise.

-Action #1: A photon goes from place to place.
-Action #2: An electron goes from place to place.
-Action #3: An electron emits or absorbs a photon."

Photons and EM waves are the same quantized phenomena, viewed in
different mathematical ways. A single photon can pass through two
slots at the same time and interfere with itself on the other side.

I wrote: "In textbooks are prsented all theories and hipothesis.
It is your choose which one do you prefer: EM, photons, QED or like sound."

So you prefer the all.
The "like sound" is the oldest and explain the all phenomena.
The new ones: EM, photons, QED explain only some. They are the fantastic
pieces to teach.
