What experiments demonstrate that light is a particle?
5 answers
Experiments utilizing a photon chamber and a moving screen in air have provided evidence supporting the particle nature of light. The photon chamber experiments, conducted with 1D and 2D gratings, revealed that light beams behave as rays, indicating their particle nature while still exhibiting wave-like distribution on detecting screens.
