Q. The energy levels of the hydrogen spectrum is shown in figure. There are some transition $A,B,C,D$ and $E.$ Transition $A,B$ and $C$ respectively represent
A) First member of Lyman series, third spectral line of Balmer series and the second spectral line of Paschen series
B) Ionization potential of hydrogen, second spectral line of Balmer series and third spectral line of Paschen series
C) Series limit of Lyman series, third spectral line of Balmer series and second spectral line of Paschen series
D) Series limit of Lyman series, second spectral line of Balmer series and third spectral line of Paschen series
Explanation
(c) Transition A $(n = \infty$ to 1) : Series limit of Lyman series
Transition B ($n = 5$ to $n = 2$) : Third spectral line of Balmer series
Transition C ($n = 5$ to $n = 3$) : Second spectral line of Paschen series
