In the photoelectric experiment, green light with a wavelength of 522 nm is the longest-wavelength radiation that can cause the photoemission of electrons from a clean sodium surface. a) What is the work function o of sodium, in electron-volts? Note kinetic energy of the emitted electron is KEm = hv - 0. b) If UV light of wavelength 250 nm is incident to the sodium surface, what will be the kinetic energy of the photoemitted electrons, in electron-volts?
