Photoelectric effect: What is photoelectric effect

What is photoelectric effect . How can it be explained from the work function. Learn its history, discovery, formula, and application. What was Einstein’s explanation. The photoelectric effect refers to what happens when electrons are emitted from a material that has absorbed electromagnetic radiation. Physicist Albert Einstein was the first to describe the ... The photoelectric effect occurs because the electrons at the surface of the metal tend to absorb energy from the incident light and use it to overcome the attractive forces that bind them to the metallic nuclei. An illustration detailing the emission of photoelectrons as a result of the photoelectric effect is provided below. The photoelectric effect is the phenomenon in which the surface of a material—typically a metal —ejects electrons when it absorbs electromagnetic radiation, usually in the form of ultraviolet or visible light.
