Calculate the ratio of the wavelength of the first and the nltimate li

1.	Calculate the ratio of the wavelength of the first and the nltimate line of the ballmer of `Li^(2+)` ?
Answer» Wavelength of the first line of the balmer series `n_(1) = 2 and n_(2) = 3` `bar v _(1)= RZ^(2)[(1)/(2^(2)) - (1)/(3^(2))] = ( 5 xx 5R)/(36) = (5R)/(4)` :. Wavelength of the first line of the bakmer series `= (4)/(5R)` Wavelength of alitimate line (limiting line) of the balmer series `bar v _(2) = RZ^(2)[(1)/(2^(2)) - (1)/(oo)] = (9R)/(4)` Wavelength of the altimate line of the balmer series `= (4)/(9R)` `:. Ratio = (9)/(5)`
