The emission, or "flash" spectrum of the solar chromosphere, created with a linear 500 lines/mm diffraction grating. The chromosphere is the close part of the Sun that becomes visible during a total solar eclipse. Instead of an absoprtion spectrum, which is what we normally see when we spread the light from the Sun using a prism or diffraction grating, the chomosphere separates out into an emission spectrum, with the brighter parts due to electrons in atoms de-exciting and giving off light of very specific wavelengths.
