====Summary====                   
{{$demo.summary}}



====Procedure====  
  - Fill the ripple tank with a shallow, even layer of water.
  - Place the wave generator so it just touches the surface of the water.
  - Turn on the wave generator to produce regular water waves.
  - Switch on the strobe light and adjust its frequency until the waves appear stationary.
  - Insert barriers, gaps, or shaped objects into the tank to demonstrate reflection and diffraction.
  - Change water depth in part of the tank to demonstrate refraction.
  - Use two wave sources to show interference patterns.

====Variations====
  * Use a phone strobe app instead of a laboratory strobe light.
  * Use different wave frequencies to change wavelength and spacing.
  * Adjust the strobe frequency slightly to show slow motion wave movement.
  * Add curved barriers to demonstrate focusing and spreading of waves.

====Safety Precautions====
  * Ensure electrical components are kept away from water spills.
  * Dry hands before adjusting electrical controls.
  * Avoid looking directly into bright strobe lights for extended periods.
  * Mop up any spilled water immediately to prevent slipping.




====Questions to Consider====
  * Why do the waves appear to stop moving when the strobe frequency matches the wave frequency? (The strobe flashes illuminate the waves at the same point in each cycle.)
  * How does changing water depth affect wave speed? (Waves travel more slowly in shallower water.)
  * What causes the pattern seen in wave interference? (Constructive and destructive interference between overlapping waves.)
  * How is diffraction affected by the size of the gap compared to the wavelength? (Diffraction is strongest when the gap is similar in size to the wavelength.)
