An electron in hydrogen atom makes a transition n1→n2n_1 \rightarrow n_2n1​→n2​ where n1n_1n1​ are principle quantum numbers of the two states. Assuming Bohr's model to be valid, the time period of the electron in the initial state is eight times that in the final state. The possible values of n1n_1n1​ and n2n_2n2​ are:
