Arthur wrote:Photons are massless and they have no rest mass. Photons are always travelling at light speed, a resting photon is complete nonsense. Photons are electromagnetic waves. You better speak of "light quantum" instead of "photon". "Photon" associates a particle and light definitely doesn't consist of particles.

The Schrödinger-Equation is tinkered in order to describe mass. I recommend instead of taking care for the Schrödinger-Equation, you better should solve the Helmholtz-Equation(s).

Arthur wrote:Yes, I can explain the photoelectric effect in terms of waves only.
In my previous post #236 I already tried to explain.
All our universe consists of electromagnetic fields. One can differ between exactly three sorts of electromagnetic fields:
First the "mass field". This is that electromagnetic field, out of that the elementary particle consists.
Second the "gravitational field". Every "mass field" causes an electromagnetic "gravitational field" around itself.
Third the "emission field", that is "light" or any electromagnetic emission.
So, light is an electromagnetic emission-field.
Every sort of these three electromagnetic fields is pure energy density.
For every point in space you can declare a certain energy density and therefor a certain force. In other words, the emission field of e.g. light is a force field the same like the gravitational field.
If light is a force-field, it can have enough energy or force in order to push e.g. an electron off its orbit, out of the atom.
This effect is known as photoelectric effect.
Einstein could not imagine, that a light beam, that was supposed to be a wave, is able to push a particle, so he invented or better: postulated a light-particle, so called "photon". But Einstein was wrong (not only in this point).

Since it is clear that photons don't exist, I avoid the word "photon" and use "light quantum" or just "quantum".
Quantums only travel in the vacuum, so the sentence above is valid. In the case a quantum meets a gravitational field of e.g. that one of an atom or molecule, the light beam is bent, so needs to travel a longer way, thus it seems to us, the light beam is slowed down and has got a slower speed. But effectively it only is bent.
Perhaps you could show me the sums?
I'm particularly interested in how you can reconcile a wave model of light with the frequency dependent workfunction and KE of emitted electrons? (in the case of the photoelectric effect)
I am not really sure, what exactly do You mean by that? What does "KE" mean?

I bet Arthur is going to trot out the semiclassical model where you treat light as a classical wave and the electron as a bound quantum state. If you do that you can reproduce many of the statistical properties of the photoelectric effect - Poisson emission stats, threshold frequency etc. It's remarkable how much you can indeed derive this way.
Unfortunately, as far as I can remember, you can't derive anti-bunching. So I'm afraid we're stuck with photons.
