  • 1) Demonstrate parallel wavefronts and their reflection on a variety of differently shaped surfaces.
  • 2) Demonstrate the refraction of waves when the parallel wavefronts change wave speed when the water depth is changed.
  • 3) Demonstrate parallel wavefronts as they diffraction around a barrier. Demonstrate the interference of the wave produced by two point sources.
  • Time-consuming setup and takedown. Needs at least 3 electrical outlets.
