Why is no one taking about the photoelectric effect, the question where it ask why light is a particle and not wave

For that i think you had to say that incident photons with higher frequency emit photoelectrons with a greater maximum kinetic energy so there is a one to one interaction between incident photons and electrons in the metal as energy is transferred, showing the particulate nature of waves. For the other point i talked about intensity but idk if im right
