Look at light rays magnified by a lens. Notice how light converges after it leaves the lens. Examine how curvature and thickness of a lens affect focal length. This learning object is one in a series of three objects. The series is also packaged as a combined learning object.
Objective
Students identify that light rays change direction when they pass through a lens.
Students demonstrate that the focal length of a lens is related to the curvature of its surfaces.
