Light illuminates a metallic surface with a work function of 1.20 eV. It takes 1.6 V of impeding potential across the phototube to stop all of the photoelectrons from reaching the opposite plate. a) Describe, in words, the process you would follow to find the maximum speed of the photoelectrons as they are emitted. ( b) State the speed you find when following your process. (. c) What would happen if you changed the metallic surface to one with a lower work function? d) What would happen if you used a light with a longer wavelength? A shorter wavelength? (
