A) Absorption line of Balmer series and the ionization potential of hydrogen
B) Absorption line of Balmer series and the wavelength lesser than lowest of the Lyman series
C) Spectral line of Balmer series and the maximum wavelength of Lyman series
D) Spectral line of Lyman series and the absorption of greater wavelength of limiting value of Paschen series
Correct Answer: A
Solution :
| [a] D is excitation of electron from 2nd orbit corresponding to absorption line in Balmer series and E is the energy released to bring the electron from $\infty $to ground state i.e. ionisation potential. |
