Planck's Constant?
 

Do radio waves occur in photons, as some would claim, or
are photons just a facet of being generated from subatomic
actions?

For example, assuming that the Big Bang is true, in the short
time afterwards, there were no subatomic particles but there
would seem to have been a massive outward flux of energy.

If radio waves are generated as photons, are they generated
in phase, and how much energy is associated with each photon?

(Just a couple of off-the-cuff thoughts to provoke seemly
and gentlemanly technical discussion)

All electromagnetic energy can be viewed as having the properties of
particles (photons) or the properties of waves.

What electromagnetic energy actually is is still an open question.

For example, assuming that the Big Bang is true, in the short
time afterwards, there were no subatomic particles but there
would seem to have been a massive outward flux of energy.

I'm not going to type in details of something already existing and
easily read:

Electromagnetic energy has phase in the wave model, not the particle model.

The energy of a photon is the frequency times Planck's Contant.

Except for what electromagnetic energy actully IS, all this has been
settled decades ago, is easily looked up, and is as suitable for
discussion as what is 6 divided by 3.

Perhaps photons from a 1MHz source are 300 metres in diameter,
but from a blue laser 300 nm in diameter.

It's more a matter of observation than of generation. Try to think
simply of electromagnetic energy (one of the 4 basic forces). If you look
for wave-like behaviour, then that's what you'll see. Ditto for
particles. It's called wave-particle duality. I don't know if there's any
easy way to demonstrate particle behaviour at RF energy levels, which is
why we tend to describe RF energy in terms of wavelength or frequency.
Similarly, it's not easy to observe or measure wave-like behaviour with
X-rays or gamma rays, so they are normally described in terms of their
photon energy in MeV, GeV, etc.


For example, assuming that the Big Bang is true, in the short
time afterwards, there were no subatomic particles but there
would seem to have been a massive outward flux of energy.

Again, you need to think in terms of observation rather than generation.
The energy of each photon is given by the simple formula
E = hf, where h is Planck's constant and f is frequency.
