Vedclass · Answer

(C) Transition $A$ occurs from $n = \infty$ to $n = 1$. This represents the series limit of the Lyman series.Transition $B$ occurs from $n = 5$ to $n = 2$. The spectral lines of the Balmer series are given by transitions from $n_i$ to $n_f = 2$. The first line is $n=3 	o 2$,the second is $n=4 	o 2$,and the third is $n=5 	o 2$. Thus,$B$ is the third spectral line of the Balmer series.Transition $C$ occurs from $n = 5$ to $n = 3$. The spectral lines of the Paschen series are given by transitions from $n_i$ to $n_f = 3$. The first line is $n=4 	o 3$,and the second is $n=5 	o 3$. Thus,$C$ is the second spectral line of the Paschen series.

The energy levels of the hydrogen spectrum are shown in the figure. There are some transitions $A, B, C, D$ and $E$. Transitions $A, B$ and $C$ respectively represent:
