    Frequency of the series limit of Balmer series of hydrogen atom in term of Rydberg constant R and velocity of light c is

    A)  \[\frac{4}{Rc}\]                                               

    B)  4 Rc

    C)  \[\frac{Rc}{4}\]                                               

    D)  \[Rc\]

    E)  \[\frac{Rc}{2}\]

    Correct Answer: C

    Solution :

                     The frequency of Balmer series \[v=Rc\left( \frac{1}{{{2}^{2}}}-\frac{1}{{{n}^{2}}} \right)\] For series limit \[n=\infty \] \[v=\frac{{{R}_{c}}}{4}\]
