MediumDefine threshold frequency.
(N/A) The threshold frequency is defined as the minimum frequency of incident radiation (light) required to eject photoelectrons from the surface of a metal.
If the frequency of the incident light is less than the threshold frequency,no photoelectric emission occurs,regardless of the intensity of the light.
It is denoted by the symbol $\nu_0$ and is a characteristic property of the metal surface.
