The photoelectric effect is the emission of photoelectrons from a clean metal surface due to incident light whose frequency is greater than a threshold frequency. This phenomenon cannot be explained using a wave apporach to light, and its explanation led to the development of the photon or...

Why does the concept of a threshold frequency for metallic surfaces support the particle theory of light? I understand why it conflicts with the wave theory, but why does it support the particle theory?? Any help would be gr8! Minnie, xoxo.
