Conceptual Physics Alive: Reflection and Refraction

Conceptual Physics Alive: Reflection and Refraction includes a digital video and questions set with answers. Observe Paul Hewitt teach in a classroom with real students, using engaging demonstrations and artwork. In this video, mirrored and diffuse reflection are compared. Refraction is demonstrated using a water tank. The concepts of total internal reflection and light dispersion are discussed, leading to a demonstration of properties of a rainbow. Segment length: 41 minutesReflection and Refraction Includes: Hewitt begins with the game 'Fermat's Principle of Least Time' (which is in the college edition of Conceptual Physics, but not in the high school version). The principle of reflection; the angle of incidence equals the angle of reflection. Diffuse reflection for rough surfaces. On the chalkboard, Hewitt draws a candle in front of a mirror and sample light rays to illustrate the law of reflection. Refraction is illustrated on the chalkboard by Fermat's principle of least time, a
