28 окт. 2024 г. · The minimum frequency of incident electromagnetic radiation required to remove a photoelectron from the surface of a metal. |
The threshold wavelength and frequency are related to the minimum energy required to produce a photoelectric effect in a given material. |
The following graph shows the variation of stopping potential V0 with the frequency v of the incident radiation for two photosensitive metals X and Y. |
14 окт. 2021 г. · The threshold wavelength is λ0 which is larger then λ. Find the number of photoelectrons emitted before the emission of photo electrons stops. |
