Hey! Foreign music is a particular electromagnetic wave, which is a form of energy and a unified structure of light. It is the minimum amount of energy required to remove an electron from a metal surface with zero kinetic energy. This energy is represented by the wavelength of the light, and the minimum frequency of radiation needed to remove the electron is called the threshold frequency.
The photoelectric current becomes constant after reaching a certain value of accelerating potential, known as the saturation current. The saturation current increases with the intensity of radiation and the accelerating potential. On the other hand, the retarding potential experiments confirm that the electron’s maximum kinetic energy occurs when the retarding potential is zero
