Question

define the term thre shold frequency and threshold wave length.​

Answer 1

Answer:

The photoelectric effect is a phenomenon in which when light arises on a metal's surface, electrons are ejected from it. These electrons released are known as photoelectrons. The Threshold frequency is known as the minimum wavelength for the photoelectric effect that the light should have

Explanation:

please mark me brain list

Answer 2

The threshold frequency is the minimum frequency of the light required to remove an electron out of metal. Since the wavelength of light is inversely proportional to its frequency, the threshold wavelength is the maximum wavelength of the light for which the metal will emit electrons.

Hope the answer helped you out!
