Photoelectric effect invented by
WebThe photoelectric effect is a phenomenon in physics.The effect is based on the idea that electromagnetic radiation is made of a series of particles called photons. When a photon hits an electron on a metal surface, the electron can be emitted. The emitted electrons are called photoelectrons. The effect is also called the Hertz Effect, because it was … WebWhen electromagnetic radiation like light falls on a metal surface then the eje ction of electrons from the metal surface occurs which is called the photoelectric effect. There is a photoelectric formula or equation by Einstein. The minimum frequency of the incident light that is required for the ejection of electrons for producing a photoelectric effect is known …
