question

The wavelengths of lines in emission and absorption spectra are measured by a spectroscope which is calibrated from the sodium - D - lines. These are two of the lines in the yellow emission from heated sodium metal. Calculate the energy of the electronic transition associated with one of the sodium - D - lines whose wavelength is 5890 \AA.
