What is spectroscopy?

• an analysis of the way in which atoms absorb and emit light
• a study of the geometry of rainbows
• the use of CCD's to capture light more efficiently than with photographic film
• a method to freeze atmospheric turbulence for better resolution

• a rainbow with some bright lines on top of the continuum.
• an unbroken rainbow of colors.
• a series of bright, colored lines.
