| My view is de Broglie's on photons. I see them as complex

Whilst I concur with "harmonic oscillators in motion"
  http://www.androcles01.pwp.blueyonder.co.uk/AC/AC.gif
  http://www.androcles01.pwp.blueyonder.co.uk/AC/Photon.gif
  http://www.androcles01.pwp.blueyonder.co.uk/photon.gif

inasmuch as a spinning bullet has energy in the spin and
energy of forward motion, I cannot agree to the ratio 1/2.
If one travels alongside the spinning bullet then it has no energy
of forward motion (which is necessarily relative) but retains
its energy of spin.

> The equivalent mass of a photon is  m = 2E/c^2,

Yes. Obvious and perfectly explained by relativistic Newtonian.

BUT!....
An object falling in a gravitational field accelerates alongside
an object with the same mass or twice that mass.
A photon of mass 2 will curve exactly the same as a photon
of mass 1. Therefore the mass or (mass equivalent) is irrelevant.

| This does not take into account that the permanent half-half
| equilibrium of the photons energy (directed half plus oscillating
| inert half) continuously takes up the slack so that v can equal no
| other velocity than c.

You've misunderstood, v is the velocity of the Earth at right-angles
to the direction of the light and is approximately 0.0001c.
sin(v/c) ~= v/c for small angles. This has nothing to do with the
intrinsic oscillation, it is strictly the Coriolis effect.

| Any energy added adds to both halves and any energy expended
| subtracts from both halves.

| This is what the de Broglie photon structure reveals.

| Agreed.
