Question

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