Maxwell’s equations do not show how an em wave spreads out. The inverse sq law spread is only valid for point source spherical waves. Maxwell’s equations are equally valid for plane waves, which do not spread out. Photon equations in qft use Maxwell’s equations

I am a simple fella and was thinking in terms of a dipole or monopole transmitters and point source waves.


 

Quote from: flummoxed on 28/04/2019 14:33:17Are you viewing the photons in a quantized radio wave as individual photons, or something else? They are individual photons. Not so obvious as the low energy means they are in the thermal noise and you need cooled detectors to find them.

You wouldn't happen to have a reference for this experiment that you could post ?

how do you depict the particle STRUCTURE of a Planck's EM photon, Einstein's EM photon, QM photon, QED photon, QFT photon or a string photon.

They are all photons/quantum fluctuations explained by different mathematical models. None of which give a picture of what the quantum fluctuation looks like in space. They just make mathematical predictions based on known/assumed properties derived by measurement. The way the experiment is set up influences what is measured.

Are all based on Maxwell's expanding electromagnetic field? I can read through physics rhetoric. The field structure has precedence. Do you know the meaning of the word precedence?

Do you know the meaning of the word precedence?

Yes.
Do you know the meanings of the words "evidence" and "credible"?

an special relativity explain red and blue shift of objects with no mass

Yes.
https://en.wikipedia.org/wiki/Relativistic_Doppler_effect

Would I be correct in thinking that a blue shifted unicorn would spin faster than a red shifted unicorn?

I think the question has been partly answered on another thread, if you try and increase the energy of an object travelling at c, or close to c, the mass / inertia must increase. In the case of the photon this must be the inertia parameter increases, this increases the photons momentum.

Which leaves a little bit of a slippery picture.

These links give a much better picture of how photons work, than any of the descriptions on this thread.

Excellent, frees us up from having to respond to your other posts eg https://www.thenakedscientists.com/forum/index.php?topic=76713.msg574595#msg574595 and https://www.thenakedscientists.com/forum/index.php?topic=76916.0

I have a great deal of respect for the Van, but if you understand what is in the links you quoted then you know that they are essentially saying the same as we’ve been saying.

I didn't think anyone had to respond to anything. Did you have a reference to what you claimed ref individual photons in radio waves being detected, using an ultra cold detector? I cant find one, were you making it up? Guess I will never know. Good night
