Lenses

Learn how incident light rays parallel to the principal axis of a thin convex lens will be refracted and converge toward a common location on the transmitted side of the lens, called the focal point. Incident light rays parallel to the principal axis of a thin concave lens will be refracted and diverge as if they originated from a focal point on the incident side of the lens. Use ray diagrams to determine the location, type, size, and orientation of images formed by lenses.
