In hydrogen atomic spectrum, a series limit found at `12186.3 cm^(-1)`. Then it belongs to.

A

Lyman series

B

Balmer series

C

Paschen series

D

Brackett series

Text Solution

Verified by Experts

The correct Answer is:
C

Series limit is the last line of the series ie, `R_(H) ((1)/(n^(2)))=barv` for series limit.
`barv=12186.3 =(109677.76)/(n_(1)^(2)) rArr n_(1)^(2)= (109677.76)/(12186.3)=9 rArr n_(1)=3`. The line belongs to Paschen series.
