80. photoelectrons liberated from the metal surface, fully retained by applying a reverse voltage U0 = 3 V. The photoelectric effect for the metal begins at the frequency of the incident monochromatic light ν0 = 6 ∙ 1014 s-1; To determine: 1) the electron work function of the metal; 2) the frequency of the applied radiation.
