"WebIn 1905 Albert Einstein was able to provide an explanation of the photoelectric effect. He proposed that light acts like a particle having energy equal to nf, where n is Planck's constant and f is the frequency of the incident light. These particles of light, called photons or quanta collide with and transfer energy to the electrons in the metal. " - Photoelectric effect byjus
