Geometric Optics: Reflection

What does a mirror tell us about light? Illustrates 11 computer-animated video units for one aspect of light's behavior-reflection. Euclid's geometric optics and his findings on the perception of distance and perspective lead to a discussion of the Law of Reflection, linking angle of incidence with angle of reflection, and the concepts of absorption, transmission, and diffuse reflection. Explains the principles involved with plane, concave, and convex mirrors, including vertex, principle axis, center of curvature, radius of curvature, and virtual image. Shows a group of "mirror equations" how an object's location can be determined by using the laws of reflection.
