There is only one logical explanation: the diffraction rings appear, one way or other, because of the positive ions inevitably present in a metal lattice strafed with energetic particles. Firstly this variant should be verified by diffractograms through earthing thin metal foils (or even through metal foils connected to a weak source of free electrons), ...

Bragg appears to to try to explain wave-particle duality by waving his hands rapidly. The moment of observation (the present) is now. Extrapolating backwards in time from that moment (when I observe a particle) I can deduce that this thing I observed was a particle in the past. But I cannot deduce much about its future - the further out you try to predict, ...

What Bragg meant by now, I cannot know. There is a huge amount of writers who meant all sort of things, and it's impossible to know all these views. The question whether the quantum system (quantum particle) is a wave or is a particle, preoccupies the physicists even today, 91 years after de Broglie formulated his $\lambda = h/p$ formula. You see, both ...

First at all light is electromagnetic radiation. To produce EM radiation you need excited electrons (or protons or some of this stuff), they emit photons. The light you see is thermal radiation from sun, laser, LED, light bulb. Then ever one detect light in detail he will end with the detection of photons. The first who claimed that light consists of quanta ...

I refer to your main questions, 1) the function $ξ$ I have written above is the wave function $\psi$ from the quantum mechanics with $s$ acting as $x$ (in $\psi$)? If not, then what is the relation between them? If you would have written the function $ξ$ correctly as in the article about the 2slit experiment, yes, the amplitude on the screen were given ...

The functions you write down are solutions of Maxwell's equations (if you think of them as lone, Cartesian components) and, as such, have an exact relationship the one-photon quantum state of the quantum photon field. Now, whether this is a photon wave function depends on your definitions. If you want to write down the quantum state of a one-photon, so ...

The experiment is meant to show the wave-particle duality of light. When light goes through a slit, it is attracted gravitationally by the side-walls of the slit and seems to curve around the exit corners. Since light is radially projected, some light smears along the sidewall of the slit also and is refracted, though this amount of light is negligible when ...

She means to say that it would behave as if both the slits were open and fall on the screen according to the double slit pattern. The entire double slit pattern comes from interference.

The radiative transfer equation is a simplified model for describing light transfer. Of course it is possible to derive the radiative transfer equation by the Boltzmann equation for a photon density function $f(x,t)$: $$\partial_t f(x,t) + v_x \partial_x f(x,t) = (\partial_t f(x,t))_{coll}.$$ Here, the term $(\partial_t f(x,t))_{coll}$ is the gain and ...
