Photoelectric effect Photoelectric effect is the phenomenon of emission of electrons from a metal surface , when radiation of suitable frequency fall on them . The emitted electrons are called photoelectrons and the current so produced is called photoelectric current. i. With the increase of intensity of incident radiation on photoelectrons emitted by a photo […]
