Ripple Generator and Strobe Light

Product Code: WA-9896


This integrated ripple generator and strobe light source, make demonstrating wave phenomena affordable, reliable and easy when paired with the Ripple Tank (WA-9897). But best of all, students can clearly see and learn about wave patterns and their interactions like never before.


  • The white LED produces a bright, clear wave pattern, and stays cool during operation.
  • The strobe and rippler are controlled by the same unit, making it possible to introduce a small frequency difference between the strobe and rippler, and causing the waves to appear to move slowly.
  • The rippler uses voice coil actuators for precise and silent operation.
  • A simple switch changes the phase of the two ripplers from 0 to 180 degrees.
  • The frequency range includes those important low frequencies that make refraction more prominent.
  • The rippler has knobs to easily adjust the dipper depth and the amplitude of the dipper stroke.


  • Speed of Wave Propagation
  • Superposition of Waves
  • Effects of Varying Water Depth
  • Reflection, Refraction and Diffraction
