Or to a charge changing energy state, which is not necessarily
associated with motion.

Something other that 0.511 MeV ? <rhetorical>


Oftentimes I can even identify the host atom as sodium or neon.

Sodium or neon emission lines are due to electrons in those
atoms changing energy state.

What is the source of this 'light from nowhere' you are suggesting?

Not from "nowhere". The electron emits it. The electon
loses energy in a single jump, and emits a single packet
of energy as a photon. It's a single event.

That's closer.


The problem is that you and Dennis B (others, such as Ken Seto)
think that the emission of a photon of energy hf comes from the
electron wiggling back and forth between those energy
levels at frequency f.

You don't know what I think but we all know what Heisinberg tho't
because he wrote it down.



Incorrect picture. One jump. No wiggle.

Does it spontaneously emerge on a path like a halluncination?
Where does it learn its frequency ?

From the energy. Planck's constant fixes the frequency associated
with a given energy change.

Can you give an example ?

A hydrogen electron jumps down from the N=4 shell to the N=2
shell. The energy change is 4.09 * 10^-19 J, or 2.55 eV. The
corresponding photon has frequency 617 THz, wavelength
487 nm.

One jump. No wiggle.

OK... You are comparing a quantum description with a classical
term. QM doesn't have a way to describe the motion because our
experience (Uncertainty principle) has taught us the classical
description is too fuzzy at that scale.

Use of a formalism that can ignore the motion does not make
the motion disapper.

Now if you'll excuse me, I have to go wiggle some loosely bound
electrons on my cell-phone antenna with complete confidence
that no objects will jump, but light will leap. :o)
