Webb20 juli 2024 · The photoelectric effect is the emission of electrons from matter upon the absorption of electromagnetic radiation, such as ultraviolet radiation or x-rays. Your source for the latest research news WebbThe photoelectric effect is the process whereby the energy from electromagnetic radiation, such as visible light, gamma radiation or other, hits an atomic electron whereby the energy of the radiation is transferred in its entirety to the electron causing the electron to be ejected from the atom.
WebbThe 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.[1] When a photon hits an electron on a metal surface, the electron can be emitted.[2] The emitted electrons are called photoelectrons.[1] The effect is also called the Hertz Effect,[3][4] because it … WebbThe photoelectric effect is a phenomenon in physics.
