Ripple tank
Product Code : SCL-ES-12773
The Ripple Tank by Educational Instrument India is a practical physics laboratory apparatus designed to demonstrate wave motion on the surface of water. It is widely used in school physics laboratories, college laboratories, STEM classrooms, and technical institutes for studying reflection, refraction, diffraction, interference, wavelength, frequency, and wave propagation.
This apparatus allows students to observe water wave patterns clearly and understand how waves behave when they meet barriers, pass through openings, or move from one region to another. By using a ripple generator, light source, and transparent tank, wave patterns can be projected onto a screen or surface for easy classroom demonstration.
The Ripple Tank is an excellent teaching aid for explaining wave theory through visual experiments. It helps students connect theoretical concepts with real observations, making wave physics easier to understand and more engaging.

How to Use Ripple Tank
Place the Ripple Tank on a stable laboratory table or demonstration bench.
Fill the tank with clean water to the recommended level.
Set up the light source above or below the tank as per the model design.
Connect the ripple generator or wave source to a suitable power supply if required.
Start the wave generator to produce regular ripples on the water surface.
Use straight or circular wave sources to create different wave patterns.
Place barriers, slits, or obstacles in the tank to demonstrate reflection, diffraction, or interference.
Observe the wave patterns directly or projected onto a screen or surface.
Record observations and discuss wavelength, frequency, and wave behaviour.
After the experiment, switch off the equipment, drain the water, clean the tank, and store all accessories safely.
Educational Importance
The Ripple Tank is an important apparatus for teaching wave behaviour in a visual and practical way. It helps students understand how waves travel, reflect, bend, spread, and interfere. Concepts such as wavefronts, wavelength, frequency, wave speed, reflection, refraction, diffraction, and interference can be clearly demonstrated using water ripples.
This apparatus supports hands-on learning and improves conceptual understanding of wave motion, sound waves, water waves, and light wave behaviour.
