Answer:
(e) Ejection of electrons
Explanation:
The best description of Einstein's explanation of the photoelectric effect is (e) Ejection of electrons from certain metals occurs when the energy of an incident photon is greater than a certain minimum.
Einstein's explanation revolutionized our understanding of light by introducing the concept of light quanta, later called photons. These photons transfer their entire energy to electrons, and if this energy is greater than the binding energy of the electron in the metal (work function), the electron is ejected. The energy of the photon is related to its frequency, so there is a minimum frequency (threshold frequency) required to eject electrons.
