🤓 Based on our data, we think this question is relevant for Professor Hempstead's class at York University.

What is the frequency in Hz of the photon released when a hydrogen atom undergoes a transition from the excited state where n = 2 to the state where n = 1?

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.
