When an electron in a hydrogen atom makes a downward transition from $n=5$ to $n=3$, the emitted spectral line corresponds to the

Professor PC Thomas Classes · Answer

(b) : Transitions terminating at $n=3$ generate the Paschen series. The first line of this series corresponds to $n=4 	o n=3$, the second line corresponds to $n=5 	o n=3$, and so on. Therefore, the transition from $n=5$ to $n=3$ is the second line of the Paschen series.
