Web1 apr. 2024 · The photoelectric effect is the process in which electromagnetic radiation ejects electrons from a material. Einstein proposed photons to be quanta of electromagnetic radiation having energy \(E=h\nu\) is the frequency of the radiation. Web12 jun. 2024 · In a photoelectric effect experiment, a monochromatic light source emitting photons with energy greater than the work function of the metal under test is used. If the …
WebIf f > f t, then a single light quantum (called a photon) of energy E = h f is sufficient to liberate an electron, and any residual energy carried by the photon is converted … Web5 Answers. In the photoelectric effect, photons incident on the cathode cause the emission of electrons. Assuming there is a sufficient electric field, these electrons will make their way across to the anode, contributing current. For simplicity, let's assume every photon generates a photo-electron.
