17. It takes 254 kJ/mol to eject electrons from a certain metal surface. What is the longest wavelength of light (nm) that can be used to eject electrons from the surface of this metal via the photoelectric effect 18. Why does this question ask you about the 'longest wavelength of radiation, rather than the 'shortest'? 19. When radiation of wavelength 2.45 x 10'm falls on a metal surface, the maximum kinetic energy of the emitted electrons is found to be...
