"One further point which may be of interest regarding the various forms of electromagnetic waves that I mentioned, namely visible and invisible light, radio signals, X-rays, gamma rays, microwave radiation, and any kind of electrical signal."
Al, glad to see you hop on board the photon train. Compare and contrast what I wrote last year on this very subject on this very thread, to whit,
"All electromagnetc waves are comprised of photons. I.e., not only is visible light on the electromagnetic spectrum made of photons, but also X- rays, gamma rays, HF radio waves, SHF radio waves - everything on the electromagnetic spectrum. Including audio signals. They’re all photons."
Is there an echo in here?
😀
cheers
