Summary: Is 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...

Summary: Often envisioned as tiny packets of energy, light must also be studied in terms of its kinetic properties. This program explores aspects of light using both wave and particle models, emphasizing that neither one fully explains all known electromagnetic phenomena. With helpful diagrams and real-world examples, the film illustrates three principal kinds of optical behavior-straight line...

Summary: What does a mirror tell us about light? This cluster of 11 computer-animated video units delves into one aspect of light's behavior-reflection. Euclid's geometric optics and his findings on the perception of distance and perspective lead to a discussion of the Law of Reflection-linking angle of incidence with angle of reflection-and the concepts of absorption, transmission, and diffuse...
