The difference in frequencies of series limit of Lymen series and Balmer series is equal to the frequency of the first line of the :

Answer»

Lymen series
Balmer series
Paschen series
Brackett series.

Solution :Let `v_(1) and v_(2)` REPRESENT the frequencies of the series limit of Lyman series and Balmer series, then
`hv_(1)=E_(alpha)-E_(1) .......(1)`
`hv_(2)=E_(alpha)-E_(2) .........(2)`
`hv_(1)-hv_(2)=E_(2)-E_(1)`
But `E_(2)-E_(1)=hv`
`or hv_(1)-hv_(2)=hv`
`v_(1)-v_(2)=V`
where v is the FREQUENCY of the first line of Lyman series.
