    The diagram shows the energy levels for an electron in a certain atom. Which transition shown represents the emission of a photon with the most energy?        

    A)  I

    B)  II     

    C)  III

    D)  IV

    Correct Answer: C

    Solution :

    [c] \[\Delta E={{E}_{0}}\left[ \frac{1}{n_{1}^{2}}-\frac{1}{n_{2}^{2}} \right]\] Here (Ist) transition represent absorption not emission. So, [c] is correct option.
