    What is the ratio of wavelength of radiations emitted when an electron in hydrogen atom jump from fourth orbit to second orbit and from third orbit to second orbit [MH CET 2004]

    A)            27 : 25                                     

    B)            20 : 27

    C)            20 : 25                                      

    D)            25 : 27

    Correct Answer: B

    Solution :

               By using \[\frac{1}{\lambda }=R\,\left[ \frac{1}{n_{1}^{2}}-\frac{1}{n_{2}^{2}} \right]\]
