It appears you saying a photon has mass.

It helped, but I have a few questions.

It also has spin, but since it doesn't affect your arguments below, we can ignore it for now.

snip.

The third effect is dependent on both the periodic transverse extension and the forward velocity of the photon. The relationship of the periodic transverse field extension and the distance traveled is what we call the wave nature of the photon.
You mention half-wave antenna in the second and then state the third is the wave nature of the photon. I'm not quite clear on this. Wouldn't you need to have the wave nature to affect a half-wave antenna?

You claim that we can't know the energy of a photon until we measure it. In this thread we have not been considering an isolated photon in space.
I was just responding to this:

It appeared to me that you were talking of a single photon here.

The frequency (f) of a photon is equal to c divided by the wavelength (L) and the energy (E) of a photon is its frequency times Planks constant (h). Mathematically f = c/L and E = fh or through sustitution E = ch/L. Since c and h are constants, when you measure a photon's wavelength, you are measuring it's energy. Also, don't you need to take a mesurement to determine the quantum state?

You're welcome.
