A phototube in a photoelectric device has a photosensitive element. When this element is beamed with radiation having a wavelength of 374.2 nm, electrons are emitted. The maximum kinetic energy observed for these electrons is 1.488 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 absolutely no excess energy?
