Part D: Total Internal Reflection: At certain incident angles, otherwise transparent materials become mirror like… Part C: Refraction and Perception: refraction changes the appearance of things if light has to travel from, say, water to air to reach your eyes… watch out for the 5-metre shark! Part B: Refractive Index: the amount that a light beam will refract depends on the angle of incidence and on the “refractive index” of a material… Part A: An Introduction to Refraction: what refraction is, what causes it… The Transcript (which can be used as a textbook) Law of Refraction (Snell’s Law) Questions (pdf) (This file relates to the video’s Bonus Features 1 and 2, which introduce students to the mathematics of refraction and total internal reflection).
