1.	Let `E=(-1me^(4))/(8epsilon_(0)^(2)n^(2)h^(2))` be the energy of the `n^(th)` level of H-atom state and radiation of frequency `(E_(2)-E_(1))//h` falls on it ,A. it will not be absored at allB. some of atoms will move to the first excited stateC. all atoms wil be excited to the `n = 2` stateD. no atoms will make a transition to the `n = 3` state
Answer» Correct Answer - B::D When all the H-atoms are in the ground state and radiation of frequency `((E_(2)- E_(1)))/(h)` falls on it, some of atoms will move to the first excited state and no atoms will make a transition to the `n = 3` state.
