Huygens' principle, the fact that light as a wave can be considered to be a series of point sources, can be used to explain many of properties that light waves exhibit. Use the program to illustrate the following properties of light:
  • Reflection

  • Critical Angle
  • Wave front
  • Wave propogation
  • Verify Snell's law
