How does photoelectric experiment prove the particle aspect of light in opposed to be solely wave-like?

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 ...

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 ...

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 ...

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 ...

I'm studying atomic spectras and got puzzled about light-quantization. I'll expose my effort to understand it so far. Blackbody radiation Around the year $1900$ Planck explained blackbody radiation ...

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 ...

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 ...

What do we mean when we say that it requires the particle nature of radiation i.e., photons, to explain photoelectric or Compton effect? I don't understand which particle nature is used to explain ...

Can a single photon be created in the laboratory? How do people make sure that they have really created a single photon?

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 did classical physics failed to explain the fact that in photoelectric effect, there is a threshold frequency value below which the effect does not occur? I not sure if my answer actually ...

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 ...

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 ...

Recently I have encountered several engineers who do not “believe in” photons. They believe experiments such as the photoelectric effect can be explained with classical EM fields + quantized energy ...
