    In Bohr model of hydrogen atom, the ratio of periods of revolution of an electron in \[n=2\] and \[n=1\] orbits is [EAMCET (Engg.) 2000]                                  

    A)            2 : 1                                          

    B)            4 : 1

    C)            8 : 1                                          

    D)            16 : 1

    Correct Answer: C

    Solution :

               \[T\propto {{n}^{3}}\Rightarrow \frac{{{T}_{2}}}{{{T}_{1}}}=\frac{{{2}^{3}}}{{{1}^{3}}}=\frac{8}{1}\]
