Wave and particle nature of light during detection in a single-photons double slit experiment
I am just a curious physics student. This question is about the nature of light.
In a single-photons double slits (or multiple slits) experiment, the interference pattern or the distribution of the ...

What is difference in dual nature of light and particles? [closed]
As We know that light shoaws dual nature or I would rather say that Sometime we can explain some phenomenon using wave analogy and other with particle nature(photon analogy). Phenomena like the ...

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 ...

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 ...

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 and photons: what suggests a particle nature if we only measure resulting current? [duplicate]
I'm fairly noobish over here, but delving into the details of the major experiments. The particle nature of a photon has me stumped though. So hopefully there is already an explanation to this I have ...

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 ...

Why wave theory cannot explain photoelectric effect and provides evidence for particle nature of light?
I am able to understand how light can be modeled to have wave characteristics from Young's double slit experiment.
But I am unable to comprehend how we can understand light to have particle ...

How energy of a photon or EM wave has something to do with frequency?
While I was thinking what exactly meant by energy in quantum mechanics, I was quite shocked by the fact that it is proportional to frequency.
$$E=hf$$
Given the fundamental definition of energy in ...
