    According to the Bohr theory, which of the following transitions in the hydrogen atom will give rise to the least energetic photon?

    A)  n = 6 to n = 1    

    B)  n = 5 to n = 4

    C)  n = 6 to n = 5    

    D)  n = 5 ton = 3

    Correct Answer: C

    Solution :

    \[\because \Delta E\propto \left[ \frac{1}{n_{1}^{2}}-\frac{1}{n_{2}^{2}} \right],\]where \[{{n}_{2}}>{{n}_{1}}\]Energy of photon obtained from the transition n = 6 to n = 5 will have least energy.
