WebFeb 9, 2024 · The photoelectric effect says that the energy of a photon, if greater than the work function of a metal will liberate an electron from it. The additional energy of an electron just gets converted into the kinetic energy of the electron. Questions: Does this mean that a metal undergoing the photoelectric effect doesn't heat up due to it?

WebIt's the emission of electrons from a metal that has absorbed electromagnetic radiation like light over a certain frequency. A particle of light is called a photon, and when a photon has enough energy, it can actually knock an electron free. What happens is that the photon collides with the metal surface, hitting an electron. WebNow you can present the equation for photoelectric emission: Energy of photon E = h × f Picture a photon transferring energy to one of the electrons which is least tightly bound in the metal. The energy of the photon does two things. Some of it is needed to overcome the work function Φ.
