spectrum problem

[shobhitdimple]

For a single electron species some of the atoms of ions are in ground state some are in excited state.At an energy level p photons of energy level 2.2 eV are made incident on an atom ion.As a result the electron gets excited .When source of energy withdrawn and only atoms of ion are allowed to reach ground state then six different wavelength are emitted .Some hav energy >2.2 eV,some = 2.2 eV and some < 2.2 eV.
Q1.Calc final and initial excited state of electron Q2 min and max value of wavelength of light emitted in ground state
