AIUI, the wave / particle duality of the photon means that it has a
beginning
and an end, from the particle model.
Therefore, the wave model must exhibit amplitude modulation to have such
a
beginning and end.
What is the waveshape of such amplitude modulation?
Planck's hv gives a fixed, particular energy for each photon; so how many
complete cycles
does the photon have within its amplitude envelope?
For those who maintain that RF radiation from antennae is composed of
photons, where
does each photon end and the next one begin?
What experimental evidence is there that RF photons exist (it is easy to
show the existence
of continuous waves, of course)
These are pretty fundamental questions raised from the claim of photons
and
perhaps the inability
of the photonists to answer them is indicative of their weak and
uncertain
knoweldge of the subject area?
You can apply all those arguments to a torch (flashlight), and they will
be equally unhelpful.

Not so, for in that case the light is produced by the action of individual
atomic particles
and you cannot radiate at 1 MHz (from Wayne's example) with a single atom.

Had an MRI scan recently?


What's an MRI of a vacuum look like?

Much like the inside of Gareth's head, I expect.
