The electron in the hydrogen atom jumps form excited state (n=3) to its ground state (n=1) and the photons thus emitted irradiate a photosenstive material. If the work function of the material is 5.1eV, the stopping potential is estimated to be: (The energy of the electron in nth state is E_(n)=-13.6//n^(2)eV )

In hydrogen atom electron jumps from (n+1)th state to nth state the frequency of emitted photon is directly proportional to (n>>1)
