Photographic and photoelectric detection
Did you know?
WebA photoelectric smoke detector typically has an electric light source and a light sensor inside. Photoelectric smoke detectors are capable of detecting the way smoke impacts light, which is especially useful given that visibility is limited in a smoke-filled room. Depending on the type, the mechanism of smoke detection differs. WebPhotoelectric effect. Tools. The emission of electrons from a metal plate caused by light quanta – photons. The photoelectric effect is the emission of electrons when electromagnetic radiation, such as light, hits a material. Electrons emitted in this manner are called photoelectrons. The phenomenon is studied in condensed matter physics, and ...
