Geometric optics. Reflection

Description

What does a mirror tell us about light? This cluster of 11 computer-animated video units delves into 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. The principles involved with plane, concave, and convex mirrors are explained, including vertex, principle axis, center of curvature, radius of curvature, and virtual image. A group of "mirror equations" show how an object's location can be determined using the laws of reflection.
