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
  1. $2 \rightarrow 1$
  2. $3 \rightarrow 2$
  3. $4 \rightarrow 2$
  4. $4 \rightarrow 3$

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.
