Ripple Tank - Projection Strobe & Frequency Meter

The Ripple Tank with Projection Strobe and Frequency Meter is a premium wave demonstration system designed for secondary and tertiary science classrooms. Combining modern digital controls with a clear, visual setup, this system allows educators to vividly demonstrate key wave properties such as reflection, refraction, diffraction, interference, and the Doppler effect. At its core is a high-intensity 4-watt LED strobe and precision agitator, both powered by an integrated signal generator. This setup ensures perfect synchronisation of light and motion, producing crisp, visible wave patterns on the projection screen. Despite its advanced technology, the unit is affordably priced, making high-quality wave investigations accessible to more schools.

The tank also includes a range of accessories to support multiple experiments, such as dippers, slit bars, curved barriers, and rulers. The equipment's durable build and large display area make it suitable for whole-class viewing, demonstrations, and hands-on student investigations.

Educational benefits:

• Demonstrates complex wave behaviour with clarity and precision
• Reinforces theoretical knowledge with visual, hands-on experiences
• Enhances understanding of wave speed, frequency, and interference
• Encourages inquiry-based learning through varied experiment setups
• Supports STEM curriculum outcomes in physics and general science

Classroom application ideas:

• Illustrate wave interference using multiple-dot dippers
• Explore the Doppler effect by varying wave source and observer position
• Use convex and concave barriers to demonstrate refraction and focusing
• Allow students to investigate how wave frequency changes wave spacing
• Integrate into flipped-classroom or group-based lab activities on wave behaviour
