Optics and refraction: light angle

Interactive  |  Interactive Lesson  |  RAR

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 density of substance and curvature at the boundary between substances. This learning object is one in a series of three objects. The series is also packaged as a combined learning object.
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.
