Expert Answer
Hi Sumit,
In ground state, energy of gaseous hydrogen at room tempertaure= - 13.6 eV. When bombarded with 12.5 eV electron beam, the energy becomes, -13.6 +12.5 = -1.1 eV
i.e. electron would jump from n=1 to n=3 where
On de-excitation the electron may jump from either n=3 to n=2 givind rise to Balmer series
It may also jump from n = 3 to n =1 , giving rise to Lyman series.
