The difference in the frequency of series limit of Lyman series and frequency of Balmer series is equal to the frequency of the first line of the ...... series.

Options

A. Paschen
B. Lyman
C. Brackett
D. Pfund

Answer

B

Explanation

`(1)/(lamda_(L))=R[(1)/(1^(2))-(1)/(oo^(2))]` limit of Lyman series
`:.(cR)/(lamda_(L))=cR[1-0]" ":.f_(L)=cR`
For Balmer series `(1)/(lamda_(B))=R[(1)/(2^(2))-(1)/(oo^(2))]`
`:.(c)/(lamda_(B))=cR[(1)/(4)]`
`:.f_(B)=(cR)/(4)`
`:.f_(L)-f_(B)=cR[(1)/(1^(2))-(1)/((2)^(2))]`
