What actually causes the electromagnetic field to be quantized?
My understanding is that quantization in QM is because the wavefunctions are analogous to classical standing waves, where the boundary conditions determine the specific quantization. That's how it ...

Why do some electromagnetic waves have more than one photon?
I know that the energy of an EM wave is equal to nhv, where n is the number of photons, but why/how do the number of photons in a wave vary? If a single atom emits an EM wave with an energy of 100 ...

Does the quantum nature of light arise from its interaction with matter? [closed]
I have a desire to reconcile the results of the photoelectric effect with the Maxwellian picture of electromagnetic radiation. I wish to explore, the possibility that the quantum nature of the photon ...

Why do photoelectrons from a vacuum photocell move towards the collector plate if it is not charged? Has it been charged beforehand?
Why do photoelectrons from a vacuum photocell move towards the collector plate if it is not charged? Has it been charged beforehand, or do they simply move forwards because of the kinetic energy they ...

Photoelectric effect in space floating metal
I have read this question:
Electrical neutrality in photoelectric effect
Now the answer by HiddenBabel says:
Metals are conductors. As electrons escape, new electrons easily flow from ground ...

What produces higher frequency light?
I don't know much more than the basics of the theory, so if my question stops making sense at some point, an answer addressing that would be awesome.
From what I understand so far, photon creation ...

How does Einstein's oscillatory & quantum structure of radiation from 1909 relate to modern physics
In his 1909 lecture The Development of Our Views on the Composition and Essence of Radiation Einstein discusses two structures of "radiation":
As far as I know, no mathematical theory has been ...

Why is there a longer time lag if light behaves as a wave?
In this problem:
According to a model based on the electromagnetic theory of light, the electron absorbs all the energy that is incident on the surface within a distance of $5.0\times 10^{-11}\ \...

Is the photon's wave function the same as an electromagnetic wave (light)? [duplicate]
The first that i have been taught in Quantum Mechanics is the photoelectric phenomenon. Without analyzing it, it concludes that when we shine light at the circuit (roughly speaking), the work required ...
