Default Photons?

1. For those who suggest that RF transmissions are made up of photons,
what is the amplitude envelope of each photon, and for how many cycles
does
it exist?


Consider this. Waves and photons exist in visible light at any frequency.
If the frequency is lowered below the visible spectrum all the way down to
say, 1 MHz, at what point do the photons disappear?
Or do they just get weak?


Photons exist in visible light at MANY frequencies where such frequencies
are generated by the transition of an electron to a lower energy orbit
around an atom.

What is the mechanism by which your photons at 1 MHz are created?



I am not arguing with you Gareth. I think I am agreeing. I am lacking in
theory. I freely admit that. I am going on common sense. Photons, light
move through our atmosphere in a straight line unless reflected by air
temperature layers or mirrors. EM radiation moves through our atmosphere
in a more complex way. It is reflected by our ionosphere or might be
absorbed by something.

My receiving antenna is a shielded loop. The antenna itself is copper
and then it is covered with an aluminium shield that is grounded to stop
the electrical part of the EM transmission. This guarantees that I will
not receive any light/photons from my antenna.

It simply makes no sense to me that I am receiving any information via
light.

I would love to hear a simple explanation that explains to me why my
inverted V on 75 meters is emitting photons/light when I put 1500 watts
of power to it. I remember years ago in physics class that this
discussion came up in my college classroom. The professor told us that
EM transmission was completely different than the transmission of light.
It had occurred to me that if we built a transmitter on a frequency of
visible light that somehow light would be emitted from the antenna. He
said that there would be EM transmission but no light. I accepted his
opinion because he knew far more than myself.

I have accepted that explanation since 1968 when he was teaching that
class. What I hear being said here is that EM transmission is composed
of photons. I always thought of it as a simple electromagnetic wave,
like what we use in transformers and radio communications every day.

Again, what I hear being said here is that radio waves are just lower
frequency light waves. Really?

Not looking for a flame war, just a simple answer to my question.
