Question
The transition from the state n = 4 to n = 3 in a hydrogen like atom results in ultraviolet radiation. Infrared radiation will be obtained in the transition from
Options
A.2 → 1
B.3 → 2
C.4 → 2
D.5 → 4
Solution
IR corresponds to least value of 
i.e. from Paschen, Bracket and Pfund series. Thus the transition corresponds to 5 → 4.
