The wave number of the series limit of Lyman series is -

Options

A. `1.097 xx 10^(7) m^(-1)`
B. `2.74 xx 10^(6) m^(-1)`
C. `1.22 xx 10^(6) m^(-1)`
D. `6.86 xx 10^(5) m^(-1)`

Answer

A

Explanation

Wave number `1/(lambda) = 1.097 xx 10^(7) [(1)/(1^(2)) - (1)/(n^(2))]`
Now in series limit `lambda` corresponds to `n = oo` to `n =1`
`:.` Wave number for series that `= 1/(lambda) = 1.097 xx 10^(7)`
