Looking Through the Lens

Published on 08/29/2010

Activity Overview

Students use simulated experiments to explore ray diagrams for converging and diverging thin lenses.

Key Steps

  • Image

    Students investigate the characteristics of converging and diverging lenses.


    First, students study simulations of diverging and converging lenses to determine the relationship between curvature and focal point.

  • Image

    Next, students use simulations to explore the relationship between image distance and object distance for converging and diverging lenses.

  • Image

    Finally, students use simulations to derive the equation for the magnification of a lens. Again, they study both converging and diverging lenses.
