The period of revolution of an electron in the ground state of a hydrogen atom is $T .$ The period of revolution of the electron in the first excited state is

Options:

Answer:

Solution:

$T = \frac{2 π r}{v}$
$r \propto n^{2}$
$v \propto \frac{1}{n}$
$∴ T \propto n^{3}$
$\frac{T_{2}}{T_{1}} = \frac{2^{3}}{1^{3}} = 8$
