Calculate the shortest and longest wavelength in hydrogen spectrum of Lyman series.

Text Solution

Verified by Experts

`(1)/(lamda_("shortest")) = (109678) ((1)/(1^(2)) - (1)/(oo^(2))) xx 1^(2) = 109678 cm^(-1) rArr lamda = 9.117 xx 10^(-6)cm`
`(1)/(lamda_("longest")) = (109678) ((1)/(1^(2)) - (1)/(2^(2))) xx 1^(2) = 82258.5 cm^(-1) rArr lamda = 1.21 xx 10^(-5) cm`
