Calculate the wavelength of spectral line in Lyman series corresponding to `n_2 = 3`.

Answer

102.6 nm

Explanation

For Lyman series, `n_(1) = 1`
`:. bar(v) = R ((1)/(1^(2)) - (1)/(3^(2))) = 109677 xx (8)/(9) = 97490.7 cm^(-1)`
`lamda = (1)/(bar(v)) = (1)/(97490.7 cm^(-1)) = 102.6 xx 10^(7) cmm = 102.6 nm`
