Bohr’s Model can be used to find the wavelengths of the photons in the absorption or emission spectrum of hydrogen atom.

Using that model, find the wavelengths of the 5→2, 4→2, 3→2 and 2→1 transitions. Specify the colour associated with these wavelengths when possible. To determine the colours, use tables. If the wavelength is not part of the visible spectrum, specify if it is ultraviolet or infrared.

1. It turns out that while Bohr’s model and equation for the calculation of emission energies does not work for atoms larger than hydrogen, it does work for any atom with only a single electron, so long as we include a factor of Z2 in the Rydberg expression, where Z is the charge on the nucleus.
