Using Light: Concave and Convex Lenses

This video examines the various uses of light and the role of different types of lenses in light refraction. The way in which eyeglasses, contact lenses, and binoculars manipulate light to allow us to see better is illustrated. Other terminology includes: regular and diffuse reflection, plane, concave and convex mirrors, opaque, refraction, angle of refraction, and concave and convex lenses.
