Further explanation:Figure 1: The photon has passed through the slits (located at the left and out of the picture), and is described by its "waveform", by which I mean its state function Ψ(x,y,z,t) whose absolute square at any point is the probability that a photon would be found there,

For electrons or others non-zero-mass particles it exists, but not for photons.

You have written:"And apparently you're under the wrong impression that photons have a wavefunction" []Anyway, the document you linked doesn't show that exists a wave function which square modulus is the probability to find the photon, as Atomic wrote.--lightarrow

More generally, the normal concept of a Schrödinger probability wave function cannot be applied to photons.[57] Being massless, they cannot be localized without being destroyed; technically, photons cannot have a position eigenstate |\mathbf{r} \rangle, and, thus, the normal Heisenberg uncertainty principle \Delta x \Delta p > h/2 does not pertain to photons. A few substitute wave functions have been suggested for the photon..

Atomic-s I've only skimmed trough thread, is this the experiment you are trying to explain?...sorry, you cannot view external links. To see them, please REGISTER or LOGIN

So what I misunderstood was that the "normal" concept of a wave function doesn't apply but "A few substitute wave functions have been suggested ..."

May I suggest as the wave function, the classical electromagnetic field equation that would describe the light at high intensity passing through this region, times some very small constant.
