2.2 Sketch an experimental setup in which a silver electrode (work function 4.73eV) is sealed in a vacuum envelope with a second electrode and a voltage is applied between them to measure the photoelectric effect. If the light of wavelength 2164Å is used, what voltage is required to reduced the photoelectric current between the plates to zero? With the voltage turned off, what is the maximum velocity of electrons(m/s) emitted into the vacuum from the Ag surface?
