Wave Motion Tank – KS3+ (Refraction, Reflection & Wave Demonstrations)

The Wave Motion Tank is a clear, purpose‑designed teaching resource developed to support the demonstration and investigation of wave behaviour in school science lessons. Suitable for KS3 and above, this apparatus enables students to observe key wave phenomena including refraction, reflection, and wave motion in a simple, visual, and engaging way.

The tank is transparent, long, and narrow, providing an adequate path length for wave experiments and allowing wave patterns to be viewed clearly from the side. Its design encourages accurate observation of how waves travel, interact with boundaries, and change direction under different conditions.

Supplied with a manual wave generator in the form of a plastic block with a handle, the tank allows users to produce consistent ripples and wave fronts with ease. This simple wave source makes the apparatus ideal for both teacher demonstrations and supervised student investigations.

Dimensions: 600mm (L) × 75mm (W) × 200mm (H)

Ideal for School Science Lessons & Physics Teaching

The Wave Motion Tank is an excellent resource for teaching wave physics at KS3, GCSE, and introductory A‑Level. It provides a clear visual model that helps students connect theoretical concepts with real‑world wave behaviour.

• Demonstrating reflection of waves from boundaries
• Investigating refraction and changes in wave direction
• Observing wave motion and propagation
• Supporting lessons on energy transfer and wave properties
• Encouraging discussion through visual, hands‑on demonstrations

Simple to use, highly visual, and well suited to the classroom, this wave motion tank helps bring abstract wave concepts to life while supporting effective, engaging physics teaching.
