Devices that use photoelectric effect
WebThese make use of the photoelectric effect to convert light into electricity for running different devices. Figure 29.6 The photoelectric effect can be observed by allowing light to fall on the metal plate in this evacuated tube. Electrons ejected by the light are collected on the collector wire and measured as a current. WebModern device that use the photoelectric effect are frequently called photocells. These devices include a metal that will emit the electrons when light strikes it and another metal plate. The energy of photoelectrons can be changed by placing a voltage across the two metal plates. As the electron moves between these plates, it gains or loses ...

WebA photoemissive cell, commonly known as a phototube, makes use of the photoelectric effect, the phenomenon whereby light-sensitive surfaces give off electrons when struck by light. Photoemissive cells are sometimes called photocells or electric eyes. A phototube consists of a vacuum tube, housed in glass or quartz, containing two electrodes: a ... WebWhen light shines on a metal, electrons can be ejected from the surface of the metal in a phenomenon known as the photoelectric effect. This process is also often referred to as photoemission, and the electrons that are ejected from the metal are called …

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 solid state and quantum chemistry to draw inferences about the properties of atoms, molecules and solids. The effect has found use in electronic devices sp…
