In hydrogen spectrum, the wavelengths of light emitted in a series of spectral lines
is given by the equation,
$\frac{1}{\lambda}=\mathrm{R}\left(\frac{1}{4^{2}}-\frac{1}{\mathrm{n}^{2}}\right)$, where $\mathrm{n}=5,6,7 \ldots \ldots \ldots . .$ and ${ }^{\prime} \mathrm{R}^{\prime}$ is Rydberg's constant. Identify the
series and wavelength region.
