In Bohr model of hydrogen atom, an electron makes a transition from $\displaystyle \mathrm{n}=4$ state to $\displaystyle \mathrm{n}=1$ state and a photon of frequency $\displaystyle v$ is emitted. The frequency of photon emitted when an electron makes a transition from $\displaystyle \mathrm{n}=4$ state to $\displaystyle \mathrm{n}=2$ state in the same model is
