## Main Question or Discussion Point

In visible light, what is the spatial dimensions of the photon itself. I'm interested in the experiments they have done to prove how big the photon is.

In most cases, a photon is described by its wavelength and has physical properties that relate to that. Visible light is roughly in the range of 350 to 750 nanometers (10^-9 meters).In visible light, what is the spatial dimensions of the photon itself. I'm interested in the experiments they have done to prove how big the photon is.

Naturally, there have been any number of experiments that connect wavelength to some of these physical properties. Is there any specific "size" property you are trying to understand? Other than wavelength, a photon does not have another parameter that relates to size in the normal sense of the word. (As a quantum particle, it is bound by the Heisenberg Uncertainty Principle. It is otherwise considered to be a point particle in much the same fashion as an electron.)

size of photon particle

How big is a photon?

how wide is a photon?

How big is a photon and what does it look and behave like?
