Examples of “pseudo quantum effects” in history of physics
Are there any examples in the history of physics where a phenomenon was considered by the physics community to be not explainable by classical physics and needed a quantum explanation whereas some ...

Is a purely classical description of lasers possible?
Laser action is usually described in terms of photons and stimulated emission. In 1972, Borenstein and Lamb published a paper* claiming that lasers can be described classically on the basis of ...

Photoelectric effect as proof of the particle-like nature of photons
Why is the photoelectric effect cited as an example of a particle-like nature of photons?
The photon's not physically knocking off the electron, right?
It's supplying energy to break the bond, hence ...

Wave-like description of Compton scattering and photoelectric effect
I have found in the wikipedia page for QFT the following statement:
... Although the photoelectric effect and Compton scattering strongly suggest the existence of the photon, it is now understood ...

Why not use this experiment to test gravity's quantum properties?
If a heavy object $X$ is in superposition, let's say, at two places "at the same time", to which point is the gravitational pull of that object directed to?
This can probably not be answered without ...

Classical (or semi-classical) interpretation of photoelectric effect?
This site says that "it has recently been proven that the photoelectric effect can be interpreted classically (or at least semi-classically) in non-particle, wavelike terms". Is anyone familiar with ...

How does photoelectric effect prove that light is also a particle?
I was watching this experiment (https://www.youtube.com/watch?v=v-1zjdUTu0o) which demonstrates the photoelectric effect, but it does not make any sense to me how it proves light as a particle instead ...
