  1. The Spectroscope Lab

  2. Differentwavelengths correspondtodifferentcolors! Units: 1 nanometer= 10-9 meters!

  3. long wavelengths short wavelengths If you pass white light through a prism, it separates into its component colors. Spectrum R.O.Y. G. B.I.V !!

  4. A hot object or a hot, dense gas produces a continuous spectrum -- a complete rainbow of colors without any specific spectral lines.

  5. A hot, low density gas produces an emission line spectrum - a series of bright spectral lines against a dark background.

  6. A cooler, low density gas in front of a hot dense gas produces an absorption line spectrum - a series of dark spectral lines among the colors of the rainbow.

  7. Spectral Lines By observing the location of the emission and or the absorption lines, one can identify the element!!!!
