- Easy to carry out the experiments - Reliable and repeatable results - Excellent visual resolution of the wave front The stroboscopic lamp is fitted with an extra-bright 3W LED, which is synchronised with the surface-wave generator. The control unit is equipped with a digital display to allow starting and stopping of the synchronism of the vibrator with the lamp, the modulation of wave amplitude and its frequency. The vibrator is electro-dynamic type. The tank is provided with two adjustable feet and with an easy to-use drain pipe with a tap. Dimensions - Tank: 300x300mm, Projection Screen (overall): 300x300mm Ripple Generator Ripple generator with power adapter. Frequency: 0-50 Hz. Switch on/off with LED Digital display Vibrator - The vibrator is electro-dynamic type. White LED- 3W, white LED light source with both strobe and steady modes. Acrylic Lens Dippers - 1. Single Dipper, 2. Double Dipper, 3. Dipper for parallel waves Barriers - For experiments on diffraction, reflection and for measuring wavelength. Convex Reflector - For extra experiments on reflection. Some experiments that can be carried out: - Superficial waves on water - Wavefront - Wavelength - Propagation speed - Reflection - Refraction - Interference - Stationary waves - Diffraction - Huygen’s principle The Ripple tank is supplied in a polystyrene preformed box and includes a complete teaching guide.

The concept has been further developed to offer new features and simplicity in this MkIII design. The unit is completely self-contained with the translucent viewing screen hinging away to reveal a 12cm water tank. The tank is removable for ease of use and has an integral multi-faceted beach which virtually eliminates unwanted reflections. Illumination is from a high intensity built-in LED which can be automatically strobed in sync with the waves to give perfectly stationary images, or switched to allow the user independent control of the wave and strobe frequencies giving the impression of wave motion across the viewing screen. The unit is supplied with three robust dippers which can be easily adjusted to suit the depth of water being used. A selection of barriers shapes and lenses are also provided to enable reflection, refraction, diffraction and interference along with the focussing properties of lenses to be demonstrated. All of the accessories can be stored neatly inside the unit when not in use. Cat No. Description Price Per SWA-295-100 Ripple Tank MkIII 157.84 ea.
