An electron in a hydrogen atom makes a transition from $n = n_{1}$ to $n = n_{2}$ . The time period of the electron in the initial state is eight times that in the final state. The possible values of $n_{1}$ and $n_{2}$ are:

Options:

Answer:

Solution:

$T \propto n^{3} \Rightarrow (n_{1} / n_{2})^{3} = 8 \Rightarrow n_{1} = 2 n_{2}$ . Only $n_{1} = 4, n_{2} = 2$ fits.
