question

To measure the wavelength of lines in atomic emission and absorption spectra, one uses a spectroscope. Two lines in the yellow emission spectra of hot Na metal, the so-called sodium-D lines, are used to calibrate this instrument. If the wavelength of one of these lines is 5890 \AA, find the energy of the electronic transition associated with this line, h = 6.62 × 10^-27 erg-sec.
