प्रश्न
Explain the existence of threshold frequency of incident radiation for photoelectric emission from a given surface.
स्पष्ट करा
उत्तर
The frequency of incident radiation at which the photoelectric effect does not exist is known as the threshold frequency. The electron has no kinetic energy at the threshold frequency; it is simply ejected. Additionally, the electron is expelled with kinetic energy when the radiation with a frequency higher than the threshold frequency strikes the surface.
