What is light? How does it operate? What are its properties? Why is it so important to the foundations of our physical world? Examines the nature of light and how it's harnessed in our lives. Explains the basic properties of light and the wave model. Also, discusses the concepts of wavelength, frequency, speed, reflection, refraction, total internal reflection, and dispersion. Explains the EMR spectrum, the color of objects, and the addition and subtraction of colors.

Is light composed of waves or particles? Explores the wave model of light from its earliest roots to our modern understanding of electromagnetism in 17 computer-animated video modules. Expresses 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. Presents the Cartesian sine wave model, Huygens' principle of bending wave fronts, the electromagnetic spectrum, and aspects of particle theory. Provides an overview of diffraction, interference, polarization, and dispersion. Also explains Young's double-slit experiment.
The speed of light is constant in a vacuum, but what about in the everyday world? Examines the behavior of light as it passes through physical substances in a collection of 23 computer-animated video shorts. Outlines Ptolemy's Law of Refraction and the concept of angle of incidence by examining light's motion through air, water, glass, and other media. Explores Snell's Law by highlighting the importance of a refractive index along with displacement, deviation, dispersion, and the role of refraction in fiber optics. Studies lens types including biconvex, convex meniscus, plano-convex, and concave models, in addition to telescopes, magnifying glasses, and the human eye.
