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.

Everyday examples and laboratory experiments explain and demonstrate the concept of waves as they relate to physics. Three segments cover the characteristics of transverse and longitudinal waves and the reflection and refraction of waves. Complex physics is made clearer by the lab demonstrations.
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.
Part of the animated "Johan, the Young Scientist" series. Disbelieving that rainbows actually exist, Johan travels to ScienScape seeking clarification from Professor Hoo. Professor Hoo explains to him how rainbows are formed and helps Johan, Ani, and Moki find one that afternoon.
Using real-world demonstrations and colorful graphics, students explore how light travels and how different mediums can affect light, resulting in reflection, refraction, and absorption. The color spectrum is also discussed through the use of prisms and paints. Part of the "Real World Science" series.
