| Fraunhofer lines |
An extremely high resolution spectrograph of the Sun showing thousands of elemental absorption lines, or Fraunhofer lines. The image shown here has wavelength increasing from left to right along each strip, and from bottom to top. Each of the 50 slices covers 60 angstroms, for a complete spectrum across the visual range from 4000 to 7000 angstroms.
