### 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 ...

### 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 ...

### 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 ...

### How does gravity escape a black hole?

My understanding is that light can not escape from within a black hole (within the event horizon). I've also heard that information cannot propagate faster than the speed of light. It would seem to ...

### What is the relation between photoelectric current and frequency of incident light?

I googled it a bit and found that photoelectric current is independent of frequency(of incident light). Some further look revealed that actually "saturation current" is independent of ...

### Can entanglement be explained as a consequence of conservation laws?

This article at NewScientist magazine (subscription required) describes entangling photons by passing them through a half silvered mirror. http://www.newscientist.com/article/mg21929282.100-quantum-...

### 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 ...

### Does a photon interfere only with itself?

I sometimes hear statements like: Quantum-mechanically, an interference pattern occurs due to quantum interference of the wavefunction of a photon. The wavefunction of a single photon only ...

### How to rebut denials of the existence of photons? [duplicate]

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 ...
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 ...
