For the Hydrogen spectrum , last line of the Lyman series has frequency `v_(1)` , last line of Lyman series of `He^(+)` ion has frequency `v_(2)` and last line of Balmer series of

For the hydrogen spectrum last line of the lyman series has frequency v1 last line of lyman series of He^(+) ions has frequency V_(2) and 1^(st) line of Lyman series of He^(+) ions has frequency v_(3) then

For the hydrogen spectrum last line of the lyman series has frequency v1 last line of lyman series of He^(+) ions has frequency V_(2) and 1^(st) line of Lyman series of He^(+) ions has frequency v_(3) then

The frequency of H_(beta) line of lyman seris of hydrogen is

The frequency of H_(beta) line of lyman seris of hydrogen is

v_(1) is the frequency of the series limit of Lyman series, v_(2) is te frequency of the first line of Lyman series and v_(3) is the frequency of the series limit of the Balmer series. Then
