Three energy levels L1,L2 and L3 of a hy...

Three energy levels `L_1,L_2` and `L_3` of a hydrogen atom correspond to increasing values of energy i.e., `E_(L_1) lt E_(L_2) lt E_(L_3)` . If the wavelength corresponding to the transitions `L_3` to `L_2, L_2` to `L_1` and `L_3` to `L_1` are `lambda_3, lambda_2` and `lambda_1` respectively then

`lambda_3=lambda_1+lambda_2`

`lambda_1=(lambda_2lambda_3)/(lambda_2+lambda_3)`

`lambda_1=lambda_2+lambda_3`

`lambda_3=(lambda_1lambda_2)/(lambda_1+lambda_2)`
