The energy corresponding to one of the lines in the paschen series of H-atom is `18.16xx10^(-20)`J. Find the quantum numbers for the transition which produce this line.

Answer

6

Explanation

`DeltaE=2.18xx10^(-18)[(1)/(n_(1)^(2))-(1)/(n_(2)^(2))]`
`18.16xx10^(-20)=2.18xx10^(-18)[(1)/(9)-(1)/(n^(2))]`
On solving, n=6.
