In a hydrogen atom an electrons makes a transition from $n_1→n_2$, where n and n are the principal quantum numbers of these two states. Assuming Bohr's model to be valid, if the time period of electron in the initial state is eight times of that in the final state, the possible values of $n_1$ and $n_2$ are:

$n_1=8, n_2=4$

The correct answer is Option (1) → $n_1=8, n_2=4$
