We’re being asked to calculate the frequency (Hz) of a photon released when a hydrogen atom undergoes a transition from an excited state.

Frequency can be calculated from wavelength and the speed of light:

$\overline{){\mathbf{c}}{\mathbf{=}}{\mathbf{\lambda \nu }}}\phantom{\rule{0ex}{0ex}}\frac{\mathbf{c}}{\mathbf{\lambda }}\mathbf{=}\frac{\overline{)\mathbf{\lambda }}\mathbf{\nu }}{\overline{)\mathbf{\lambda }}}\phantom{\rule{0ex}{0ex}}\overline{){\mathbf{\nu }}{\mathbf{=}}\frac{\mathbf{c}}{\mathbf{\lambda }}}$

We’re going to use the Balmer Equation to calculate the wavelength which relates wavelengths to a photon’s electronic transitions.
