Ripple Tank
Specifications : Size: 52 x 44 x 40 cm – Weight: approx. 6.5 kg. The Ripple Tank is a very effective tool that helps students to understand wave echanics. The Ripple Tank is also used to introduce, develop and visually demonstrate wave theory such as refraction, diffraction and Interference.
Our unique system uses a pulsed air supply so that standing waves are easy to reproduce. The Ripple Tank is supplied with all accessories, including connecting cables and instruction manual. We use a unique pulsed air system to produce accurate and epeatable waves with our Ripple Tank. The electronic controller allows you to control the frequency of the pulses and hence the value of the wavelength. The controller also coordinates the same pulsed air frequency to the stroboscope so that the waves appear to be static and therefore easily measurable. The system also includes a bright light source which is easily moveable to the side of the Ripple Tank.The Ripple Tank is also used to introduce, develop and visually demonstrate wave theory such as refraction, diffraction and interference.
