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 … Visa mer The photons of a light beam have a characteristic energy, called photon energy, which is proportional to the frequency of the light.

Webb13 nov. 2024 · 2 Answers. Sorted by: 1. Anode and cathode are defined according to the direction in which charge-carriers move in the device itself, be it a battery or photocell, or a passive device such as a diode. The anode is the electrode towards which negative carriers move (or away from which positive carriers move); vice versa for the cathode. Webb8 jan. 2024 · 1. Light of a single frequency falls on a photoelectric material but no electrons are emitted. Electrons may be emitted if the A) frequency of light is decreased. B) frequency of light is increased. C) intensity of light is decreased. D) intensity of light is increased. E) velocity of light is increased. 2. WebbWhen 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 … how did chick fil a get it\u0027s name
