The wavelenght of a certain line in the Paschen series in 1093.6 nm What is the value of higher orbital for lt brgt this line .`[R=10.973xx10^(+7)m^(-1)]`.

Text Solution

Verified by Experts

The correct Answer is:
6
`(1)/(lambda)=R[(1)/(n^(2))-(1)/(n_(2)^(2)]]`
`(1)/(1.093xx10^(-6))=R[(1)/(3^(2))-(1)/(n_(2)^(2)]]`
`n_(2)^(2)=36`
`n_(2)=6`
