Learning Material  |  Interactive Lesson  |  RAR

Published on 2016 August 24th

Look at light rays travelling through air and glass. Notice how light bends as it passes from one substance to another. Try to predict whether the ratio of the angles of light will change if the direction of the light ray changes. This learning object is one in a series of three objects.

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.
