Refraction is the change in direction of a wave as it passes from one medium into another. Sure that's easy to say, but what exactly does it mean? -- This refreshing lab pairs the included acrylic light demo cube first with a ""cold frosty beverage"" type mug to demonstrate the index of refraction of water, and then helps students explore the ""lens effect"" that results from the relative indices of refraction of water and air. -- Provides students with a better understanding of Snell's Law. Developed by John B. Johnston, Director of The Faraday Center. Grades 11-12. -- Includes: acrylic demo cube, blue food coloring, instructions. Required but not included: laser, large mug. |
