The transition from the state $n=3$ to $n=1$ in a hydrogen like atom results in ultraviolet radiation. Infrared radiation will be obtained in the transition from
$2 \rightarrow 1$
$3 \rightarrow 2$
$4 \rightarrow 2$
$4 \rightarrow 3$
Solution
Infrared radiation is found in Paschan, Brackett and pfund series and it is obtain when electron transition occur from high energy level to minimum third level.
