    In terms of Rydberg constant R, the wave number of the first Balmer line is:

    A)  \[R\]

    B)  \[3R\]

    C)  \[\frac{5R}{36}\]

    D)  \[\frac{8R}{9}\]

    Correct Answer: C

    Solution :

     Wave number\[\overline{v}=\frac{1}{\lambda }R\left( \frac{1}{n_{1}^{2}}-\frac{1}{n_{2}^{2}} \right)\] Here, \[{{n}_{1}}=2,{{n}_{2}}=3\] \[\therefore \] \[\overline{v}=\frac{5R}{36}\]
