Sodium lights are often utilized in street lamps because the emitted light is essentially monochromatic, decrease blurriness in human vision that is due to astigmatism. The professed "D-line" of the sodium emission spectrum has a wavelength of 5893 Angstroms. Presuming the emission is due to an electron transition between two consecutive energy levels, compute the energy levels involved
