  4. Misdirected or misused light Inappropriate application of exterior lighting products Light causing a glow over urban/suburban areas LightPollution http://farm2.static.flickr.com/1293/554194288_965f5494cb.jpg

  5. Spectroscopy • Dispersion of light into component colors • Spectrograph- produces graph of the intensity of light as a function of color or wavelength http://loke.as.arizona.edu/~ckulesa/camp/spectroscopy_intro.html
