Question
Work function of tha metal is ?
What is the work function of the metal, if the light of wavelength 4000 Å generates photoelectron of velocity 6 x 105 ms1 from it? (Mass of electron = 9 x 1031 kg. Velocity of light = 3 x 108 ms-1 Planck's constant = 6.626 x 1034 Js. Charge of electron = 1.6 × 10-19 JeV1) %3D
