Photoelectric effect refers to the phenomenon in which electrons are emitted from a material when it is exposed to light (electromagnetic radiation) of sufficient energy. Photoelectric effect provided evidence for the quantized nature of light and supported the wave-particle duality of electromagnetic radiation. The dual nature of matter and the dual nature of radiation are important concepts states that a matter can exhibit both particle like and wave like properties. In this article, we ... Photoelectric effect is the emission of electrons when electromagnetic radiations having sufficient frequency incident on certain metal surfaces. We call the emitted electrons as photoelectrons and the current they constitute as photocurrent. The photoelectric effect is a phenomenon in which electrons are emitted from a material when it is exposed to light or electromagnetic radiation of sufficient energy. In simpler terms, it's when light shining on a surface causes the emission of electrons from that surface. Applications of Photoelectric Effect When a metal is exposed to light, metal emits electrons from its valence shell. This is called photoelectric effect . The real life applications of photoelectric effect is used in ...
