This album of eight computer-animated video segments looks at the particle approach to studying light by exploring the antithesis of the wave model. Presents black-body radiation, Planck's constant, the photoelectric effect, and the work of James Clerk Maxwell as forerunners to Einstein's concept of photon frequency. Shows examples of a slope-intercept graph and a revised double-slit experiment using light-sensitive paper segue to an illustration of the Compton effect, establishing that light consists of a stream of particles. De Broglie's contributions introduce wave-particle duality, which some might consider an inadequate solution, although it represents the best that current science can do. Accessibility options on the DVD are: (1) audio description, (2) subtitles for the deaf and hard of hearing (SDH).
