What is the wave number of 4th line in Balmer series of hydrogen spectrum ?
`R = 1, 109, 677 cm^(-1)`

A

`26630 cm^(-1)`

B

`24360 cm^(-1)`

C

`24730 cm^(-1)`

D

`24372 cm^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
D
`bar(nu) = 109677 [(1)/(2^(2))-(1)/(6^(2))]`
`= 109677 [(1)/(4)-(1)/(36)]`
`= 24372 cm^(-1)`
