Calculate the shortest wavelength in H spectrum of Lyman series, when `R_(H) = 109677 cm^(-1)`.

Explanation

For lyman series `n_(1) = 1`
For shortest `lambda `of Lyman series difference in two levels showing transition should be maximum (i.e.`n_(2) = prop`
`:. (1)/(lambda) = R_(H) [(1)/(1^(2)) - (1)/(2^(2))] = 109678`
`lambda = 911.7 xx 10^(-8) cm = 911.7 Å`
For shortest `lambda `of Lyman series difference in two levels showing transition should be maximum (i.e.`n_(2) = 2`
`:. (1)/(lambda) = R_(H) [(1)/(1^(2)) - (1)/(2^(2))] = 109678 xx (3)/(4)`
`lambda = 1215.67 xx 10^(-8) cm = 1215.67 Å`
