Einstein provided a groundbreaking explanation for the photoelectric effect in 1905, for which he was awarded the Nobel Prize in Physics in 1921. He proposed that light comes in quanta, now called photons, and that the energy of a photon is given by (E = hf), where (h) is Planck's constant and (f) is the frequency of the light. According to Einstein, the energy of the photon is used to overcome the binding energy of the electron to the material (the work function) and to provide kinetic energy to the ejected electron. i--- Mihaela Chirita Culegere Fizica Clasa 11 Pdf Fix
