AP Quiz

After some soul searching (always a difficult exercise for those of us without one), I have decided to postpone the quiz on wave behavior of light until Friday. It will include gratings and you will have to know something about the electromagnetic spectrum and dispersion. Dispersion is the fact that light of different frequencies have different indices of refraction ( travel at different speeds in matter) so they bend different amounts, thus rainbows and some of the reults from your Snel's law lab.
