A radio signal is a mixture in which groups of individual photons
form sine shaped 'bunches' which move along. ..somewhat like a water
wave except the photons move back and forth rather than up and down.

An unmodulated radio signal is monchromatic.
The photons are phase and frequency coherent.
The photons travel outward from the antenna.

Have you ever trapped an individual RF photon?

Yep. (prove me wrong!)

RF tank circuit ?

Tanks for proving me right!

It would be a *very* small tank.

I think you mean that even a small tank could hold a LOT of photons.
(tank circuit, of course)

I was assuming one wanted a tank circuit to hold a single photon. ;-)


A light quantum is on
the order of 2.5 eV. A microwave photon 1/2 cm in wavelength
would be about a million times less energetic.

Yep and a 50 KHz signal (Very low frequency, very long wave), 5.996 km
wavelength, has an energy of 2 x 10^-10 eV. Kind of hard to detect a single
photon of that energy.


This has given me an idea. Do the individual photons move or remain
at basically the same location?
I'll have to make an animation of this.

Photons move at c.

Wrt what?

Any inertial FoR in SR,

Right, of course.

the source [and very quickly any inertial FoR] in
the ballistic theory of light,

In Ritz's ballistic theory, just the source.

Correct. But Ritz's theory is on the fritz due to the lack of multiple
images of distant stars.

Not to mention it doesn't explain the brightness versus time curve of
most novae and supernovae.

Good point. The peak should be much sharper and there should be a long tail
with red shifted doppler from the gases expelled away from us.

_most_???? Is it consistent with ANY?


AQL1493 has a rather peculiar single U-shaped anomaly.
Androcles occasionally touts this as proof of something.
I don't have an explanation; it's rather inconclusive to
me personally. I suspect something else, but what it is,
I don't know.

As it is, my computations assuming Newtonia on supernovae
suggest that the peak would be very rounded; the photons
from the leading edge of the exploding sphere would reach
us first, with low but growing luminosity. The maximum
would be at the point where the light from the gases
from the cross-section of the star perpendicular to our
view line -- which is travelling at c relative to us --
reaches us. The brightness would then taper off, in a manner
much like the brightness increase, maybe a bit slower
since 1.0/.9 - 1.0 1.0 - 1.0/1.1 .

Since at least one measurement suggests an explosion speed
of 1/10 c, one can perform these calculations without much
difficulty, and the results would depend on distance.
