The electron in the hydrogen atom jumps from excited state ( 
) to its ground state ( 
) and the photons thus emitted irradiate a photosensitive material. If the work function of the material is 5.1 eV , the stopping potential is estimated to be (the energy of the electron in n th state 
Text Solution
Verified by ExpertsThe correct answer is:
D
Energy released when electron in the atom jumps from excited state 
to ground state 
is
Therefore, stopping potential
