Threshold frequency

The threshold frequency is defined as the minimum frequency of the incident radiation below which photoelectric emission or emission of electrons is not possible. The threshold frequency refers to the frequency of light that will cause an electron to dislodge emit from the surface of the metal. Photoelectrons ejected have some kinetic energy. Kinetic energy K. E is equal to half times the mass or abbreviated as m multiplied by the square of the velocity or abbreviated as v of the electrons as shown below;. The photoelectric effect is referred to a phenomenon in which electrons are expelled or ejected from the surface of a metal when light is incident on it. Electrons thus emitted are also termed as photoelectrons. Therefore, the threshold frequency is referred to as the frequency of the light which carries sufficient energy to extricate an electron from an atom. The work function of a metal is referred to as the minimum amount of energy which is required to start the emission of electrons from the surface of the metal.

The Threshold Frequency Calculator is a useful tool in physics that helps determine the minimum frequency of light required to release electrons from a material's surface through the photoelectric effect. This phenomenon, discovered by Albert Einstein, plays a crucial role in various scientific and technological applications, including solar energy conversion, photodetectors, and photoelectron spectroscopy.
