Question

Quizplus · Accepted Answer

The photoelectric effect experiment demonstrates the particle-like behavior of light because it shows that light can transfer discrete amounts of energy (quanta) to electrons in a metal, causing them to be emitted. This is only explainable if light is thought of as a particle or photon, rather than a wave.
