Question

A. The photoelectric effect experiment provides evidence in support of what important physical concept?
B. Describe how Einstein's explanation of the photoelectric effect provides evidence in support of this concept.

Answer 1

soli The photoelectric effect experiment Provides evidence in support of the quantization of light. That means a beam of light is a collection of discrete wave packets (photons). According to the theory of Photo electric effect, proposed by Einstein - a low frequency beam at a high intensity could not build up the energy required to produce photo electrons like it would have if light's energy was continuous like a wave. so, Einstein Roro explained that a beam of light is not a wave but a collection collection of photons (quanta of energy 2
