If the series limit frequency of the Lyman series is `nu_L`, then the series limit frequency of the Pfund series is

A

`(nu_L)/(16)`

B

`(nu_L)/(25)`

C

`25nu_L`

D

`16nu_L`

Text Solution

Verified by Experts

The correct Answer is:
B
For the series limit frequency of the Lyman series,
`hnu_L=E[1/(1^2)-1/(oo)]=E`
Again, for the series limit frequency of the Pfund series,
`hnu_P =E[1/(5^2)-1/(oo)] =E/(25) therefore nu_P=(nu_L)/(25)`
