Calculate the wave number of the first spectral line in the Lyman series of He^(+) spectrum |
|
Answer» SOLUTION :For first LINE in Lyman series, `n_(1) =" lower energy "= 1` `n_(2)= "higher energy "= 2` Wave number `(barv)` is given by the equation `barv=z^(2)R_(H)((1)/(1^(2))-(1)/(2^(2)))=4xx109677xx(3)/(4)=329031cm^(-1)` Wave number of first line in Lyman series of `He^(+)` is `3.29xx10^(5)cm^(-1)` |
