Calculate the wave number of the spectral line when electron jumps from the seond Bohr orbit to the ground state. R = `1.097xx 10^(7) m^(-1)`

Explanation

`1/lamda=barv=R[1/(m^(2))-1/(n_(2)^(2))]` `n_(1)=1,n_(2)=2`
`barv=1.097xx10^(7)m^(-1)[1-1/4]=1.097xx10^(7)m^(-1)xx3/4=8.228xx10^(6)m^(-1)`
Wave number of spectral line =`8.228xx10^(6)m^(-1)`
