Light Rays
Geometric Optics
Wave Theory of Light


  • Apply the Law of Reflection in controlling the motion of a reflected beam of light.
  • Use measured velocities to predict the change in direction (refraction) of a simulated wave packet as it moves from one medium to another.
  • Design and test a lens for focusing a group of simulated wave packets at a common point.

The activity uses the SAM Robot and 2 light sensors with the LabPro or CBL2.
