When ultraviolet light with a wavelength of 400 nm falls on
Last updated: 7/10/2022
When ultraviolet light with a wavelength of 400 nm falls on a certain metal surface, the maximum kinetic energy of the emitted photoelectrons is 1.10 eV. What is the maximum kinetic energy Ko of the photoelectrons when light of wavelength 260 nm falls on the same surface?
