WebbThe photoelectric effect is the emission of electrons when electromagnetic radiation, such as light, hits a material.Electrons emitted in this manner are called photoelectrons. The phenomenon is studied in condensed matter physics, and solid state and quantum chemistry to draw inferences about the properties of atoms, molecules and solids. . The … WebbPhotons and electrons Photoelectric current and stopping Potential Einstein's Photoelectric Equation Einstein looked at the way in which electrons tried to leave the metal. He established that it actually takes energy for an electron to leave the surface of the metal. He called this energy the work function, Φ.
