Optics and refraction

Interactive  |  Interactive Lesson

Look at light rays travelling through air, glass and water. Notice how light bends as it enters a new substance. Explore how the angle of refraction is affected by the type of substance and curvature at the boundary between substances. Examine how curvature and thickness of a lens affect focal length. This learning object is a combination of three objects in the same series.
Students identify that light rays change direction when they pass from one medium to another.
Students predict the angle of refraction as light passes from one medium to another.
Students demonstrate that as the incident angle of light rays changes, the angle of refraction also changes.
Students demonstrate that the focal length of a lens is related to the curvature of its surfaces.
