Photoelectric threshold wavelength of metallic silver is= 3800 Amstrong . Ultra -violet light of= 2600 Amstrong is incident on silver surface. Calculatea)the value of work function in joule and ev(ans -> 3.27eV and 5.23 x 10-19 J )b) maximum K.E of the emitted photoelectrons(ans -> 1.5 eV ) c) the maximum velocity of the photoelectrons( Mass of the electron = 9.11 x 10-31 kg)(ans -> 0.7829 x 10-6 m/s )Please show me the solution .Diksha
