Conditions for photoelectric effect
WebApr 8, 2024 · Minimum conditions for Photoelectric Effect: Threshold Frequency: It is the minimum frequency of the incident light or radiation that will produce a photoelectric effect. Threshold wavelength: During the emission of electrons, a metal surface corresponding to the greatest wavelength to incident light is known as threshold wavelength. WebThe photoelectric effect is the phenomenon where electrons are emitted from metal surfaces after they are exposed to the energy of light, visible light, or even UV rays of a preferable frequency. Photoelectrons are the electrons that are emitted by the photoelectric effect. Photoelectrons constitute a current known as the photoelectric current.
