Well let's try to wrap this up, my weekend is about over.

Ahhh, I believe I see what you've done. You seem to be using the word
"photon" for BOTH wave and particle aspects of EM radiation, rather than
reserving it only for the particle aspects. Sort of makes the word
meaningless when used in that manner, IMO.

Here are some definitions of photon:

=========================================================
http://encyclopedia.laborlawtalk.com/Photon

In physics, the photon (from Greek, meaning light) is a quantum of
excitation of the quantised electromagnetic field and is one of the
elementary particles studied by quantum electrodynamics (QED) which is
the oldest part of the Standard Model of particle physics.
==========================================================

Notice where it mentions it's one of the elementary PARTICLES.

==========================================================
I INTRODUCTION
Photon, particle of light energy, or energy that is generated by moving
electric charges. Energy generated by moving charges is called
electromagnetic radiation. Visible light is one kind of electromagnetic
radiation. Other kinds of radiation include radio waves, infrared waves,
and X rays. All such radiation sometimes behaves like a wave and
sometimes behaves like a particle. Scientists use the concept of a
photon to describe the effects of radiation when it behaves like a
particle.

Notice where it says: "Scientists use the concept of a photon to
describe the effects of radiation when it behaves like a particle."

Photons:

Established physical theory assumes light to be of a dualistic nature,
i.e. either to be described as a wave (explaining interference effects)
or as a particle (photon).
==========================================================

Notice where it says: "... or as a particle (photon).
