which is of the right frequency and phase to permit an
efficient transition to a permissible energy level.

A wide band receiver will intercept the transitions at a
higher rate due to the closing motion, just as you have
described.

Thank you.

Only crackpots would stick to the explanation according to which
"clocks which run the faster the higher they are located in the
potential, whereas the energy and frequency of the propagating photon
do not change with height."

But, nevertheless, most GRists will probably not openly recognize that
such explanation is "misleading".

LOL


Does that mean "Laughing Out Loud -or- Lots of Luck (or Love)"?

I am looking for a Pound-Rebka-Snider experiment down a
mine shaft. I think that would clear up a lot of the misunderstanding
but so far I haven't found one. Either my research skills are
getting rusty or graduate students have a softer life these days.


Misunderstandings from some GRists! And more generally from crackpots!

In the meantime, you could content yourself with the formula easily
obtained by using the potential energy of the photons:

Nu1 is the frequency of the signal sent to the bottom
of the shaft.
Nu2 is the frequency of the signal received at the bottom.
d is the distance of the bottom of the shaft to the Earth's center.
Me and Re are respectively the mass and the radius of the Earth.
The shift Nu2/Nu1 - 1 = (GMe/2Re^3c^2) * (Re^2-d^2)

If GR doesn't get the same formula, it is false.

Equation 14 looks reasonable:

It is in terms of gravitational potential so
would predict the lowest frequency at the surface
then increasing as the clock either moved up or down.
That is consistant with free pendulms, long know to
decrease in frequency when moved up or down from the
surface.

As for your equation above, Nu1 should equal Nu2.

If so then I agree with you because the paper appears
correct as it is.... to degee of showing the spacetime
interval tau instead of time, a detail many writers overlook.

"Are you saying if the paper substitutes your equation
or the one they used then it will make the paper wrong?"

As long as their equation 14 is not written in terms of Me, Re and d,
I prefer to wait and see.

A nicer form of the "shaft" shift formula is
shift = GMe/2Rec^2 * (1-d^2/Re^2),
where d is the distance between the bottom of the shaft and the
Earth's center.
The shift could of course be expressed in terms of the
shaft depth = Re-d. Replacing d by Re-depth, one gets
shift = GMe/2Rec^2 * (1-(Re-depth)^2/Re^2)

If the depth = Re, one is left with shift = GMe/2Rec^2 (1)
Let's remember that the signal is sent from the Earth's surface
to the bottom of the shaft.

Notice that a signal emitted at infinity towards the Earth's surface
would be observed to be shifted by GMe/Rec^2 (also according to GR).
The fact that this shift is twice the "shaft" shift (1) must be
more than a coincidence!
