The photoelectric effect may be a phenomenon during which electrons are ejected from the surface of a metal when light is incident thereon. These ejected electrons are called photoelectrons. It’s important to notice that the emission of photoelectrons and therefore the K.E. of the ejected photoelectrons depend on the frequency of the sunshine that’s incident on the metal’s surface. The method through which photoelectrons are ejected from the surface of the metal thanks to the action of sunshine is usually mentioned as photoemission. When light shines on metal, electrons are often ejected from the surface of the metal during a phenomenon referred to as the photoelectric effect. This process is additionally often mentioned as photoemission, and therefore the electrons that are ejected from the metal are called photoelectrons. In terms of their behaviour and their properties, photoelectrons are not any different from other electrons.


The prefix, photo, simply tells us that the electrons are ejected from a metal surface by incident light. At the point when light gleams on metal, electrons can be produced from metal surfaces in a cycle known as photoelectric impact [1]. In reference to work on radio waves, Hertz observed that, when ultraviolet shines on two metal electrodes with a voltage applied across them, the sunshine changes the voltage at which sparking takes place. This relation between light and electricity (hence photoelectric) was clarified in 1902 by another German physicist, Lenard [2]. He demonstrated that electrically charged particles are liberated from a metal surface when it’s illuminated which these particles are just like electrons, which had been discovered by British physicist Joseph John Thomson in 1897. Even though photoemission can occur from any material, its most readily observed from metals and other conductors [3]. This is often because the method produces a charge imbalance which, if not neutralized by current flow, leads to the increasing potential barrier until the emission completely ceases. The energy barrier to photoemission is typically increased by nonconductive oxide layers on metal surfaces, so most practical experiments and devices supported the photoelectric effect use clean metal surfaces in evacuated tubes [4]. Other phenomena where light affects the movement of electrical charges include the photoconductive effect (also referred to as photoconductivity or photo resistivity), the photovoltaic effect, and therefore the photo electrochemical effect he probability of the occurrence of photoelectric effect is said to the number of the radiation-absorbing material and inversely associated with the energy of the gamma-ray.


Most often photoelectric absorption occurs with absorbing material of high number and with low energies of the gamma- rays. The height within the gamma-ray spectrum produced by detecting photoelectrons is named a full-energy peak because it provides immediate information about the energy of the gamma ray. We can consider the incident light as a stream of photons with an energy determined by the sunshine frequency. When a photon hits the metal surface, the photon’s energy is absorbed by an electron within the metal. The interaction by which electrically charged particles are delivered or inside an item when it retains electromagnetic radiation
