Let \(\rm E_n=\frac{-1}{8\varepsilon^2_0}\frac{me^4}{n^2h^2}\) be the energy of the nth level of H-atom. If all the H-atoms are in the ground state and radiation of frequency (E2-E1)/h falls on it,
1
it will not be absorbed at all
2
some of atoms will move to the first excited state.
3
all atoms will be excited to the n = 2 state.
4
no atoms will make a transition to the n = 3 state.
