Calculate the wavelength of a photon emitted when an electron in `H-`

1.	Calculate the wavelength of a photon emitted when an electron in `H-` atom maker a transition from `n=2` to `n=1`
Answer» `1/lambda=RZ^(2)[1/n_(1)^(2)-1/n_(2)^(2)]` `:. 1/lambda=R(1)^(2)[1/1^(2)-1/2^(2)]` `:. 1/lambda=(3R)/(4)` or `lambda=(4)/(3R)`
