Question

In Bohr’s model of hydrogen atom, the ratio between the period of revolution of an electron in orbit n = 1 to the period of the electron in the orbit n = 2 is

Options:

A . 1 : 2

B . 2 : 1

C . 1 : 4

D . 1 : 8

Answer: Option D
:
D

\frac{T_{1}}{T_{2}} = {(\frac{n_{1}}{n_{2}})}^{3} = {(\frac{1}{2})}^{3} = \frac{1}{8}

T_{1} : T_{2} = 1 : 8
