A hydrogen sample is prepared in a particular excited state A. Photons of energy 2.55eV/atom gel absorbed into the sample to take some of the electrons to a further excited state B. As per the number of photons when an electron in the higher excited state returns to the ground state, which of the following are may not be possible?
