In this spectrum of `Li^(2+)` the difference of two energy level is 2 and sum is 4. Find the wavelength of photon for difference of these two energy state.
(note `n_(1) + n_(2) = 4 ` and `n_(2) =2` so take `n_(1) =1 ` and `n_(2) =3`

Text Solution

Verified by Experts

`lambda = 1.14 xx 10^(16) m =11.4 nm`
