Dual Nature Of Light Question 207
Question: Electrons in a hydrogen like atom $ (Z=3) $ make transitions from the fourth excited state to the third excited state and from the third excited state to the second excited state. The resulting radiation are incident on a metal plate and eject photoelectrons. The stopping potential for photoelectron ejected by shorter wavelength is 3.95 eV. Find the work function (in eV) of the metal plate.
