A phototube in a photoelectric device has a photosensitive element. When light of wavelength 389.2 nm is shone on this surface, electron are emitted with a maximum kinetic energy of 1.589 x 10^-19 J/electron. What is the wavelength of a laser which will turn the photocell on and cause electrons to be ejected which have no excess energy?
