Quizplus · Accepted Answer

Albert Einstein was awarded the Nobel Prize in Physics in 1921 for his explanation of the photoelectric effect. The photoelectric effect is a phenomenon in which electrons are emitted from a metal surface when light is shone on it. Einstein's explanation of this effect showed that light behaves as both a wave and a particle, which was groundbreaking for the understanding of quantum mechanics.
