    The ratio of minimum wavelengths of Lyman and Balmer series will be

    A)  1.25                                      

    B)  0.25

    C)  5                                            

    D)  10

    Correct Answer: B

    Solution :

    For minimum wavelength,                 \[\lambda \propto {{n}^{2}}\] \[\therefore \]  \[\frac{{{\lambda }_{Lyman}}}{{{\lambda }_{Balmer}}}={{\left( \frac{1}{2} \right)}^{2}}\]                 \[\frac{{{\lambda }_{L}}}{{{\lambda }_{B}}}=\frac{1}{4}=0.25\]
