330   $aIs light composed of waves or particles? This collection of 17 computer-animated video modules explores the wave model of light, from its earliest roots to our modern understanding of electromagnetism. Empedocles' belief that light streams from the eye, Aristotle's conception of light as a disturbance in ether, and Euclid's mathematical, ray-centered paradigms are all explored. The Cartesian sine wave model, Huygens' principle of bending wave fronts, the electromagnetic spectrum, and aspects of particle theory are also presented, along with overviews of diffraction, interference, polarization, and dispersion, and an explanation of Young's double-slit experiment.
