Answer 2

Answer:

photoelectric effect

Explanation:

The ejection of electrons when the surtace of metal is irradiated by light is called photoelectric effect

Einstein was awarded the Nobel Prize in Physics in 1921, for the discovery of the law of the photoelectric effect.

This discovery is so important because Einstein suggested for the first time that light is both a wave and a particle.

This phenomenon, known as the wave-particle duality of light, is fundamental to all of quantum mechanics and has influenced the development of electron microscopes and solar cells.
