A sample of hydrogen gas has some atoms in one excited state and some atoms in other excited state .It emits three different protons . When the sample was irradiated with radiations of energy 2.85eV, it emits 10 different photons , all having energy equal t o or less than 13.4eV (a)Find the principal quntum numbers of initially excited electrons (b)Find the maximum and minimum energies of the initially emitted photons.
