1 LASCELLS MINI RIPPLE TANK This compact unit provides an excellent way to demonstrate the wave properties of reflection, diffraction, refraction and interference with none of the setting-up problems usually associated with ripple tanks. 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.

Comprises a tough, moulded frame with a large transparent viewing surface. The Ripple Tank light source is a 6V halogen lamp which gives excellent illumination. The tank has sloping sides which minimise noise. 2xAA batteries and a 12V power supply are required. This Ripple Tank System comes complete with:

3 RIPPLE TANK - STANDARD - NEW! A good quality ripple tank kit, to allow demonstration of the basic properties of waves and wave propagation. The shallow water tank is illuminated from above, so the light shines through the waves in the water, appearing as shadows below. The wave shadows are then reflected by an angled, fixed mirror below the tank, onto an attached vertical frosted screen. The ripples in the water above now show up as shadows on the screen, giving a clear visual demonstration of the behaviour of waves. Waves are generated using the control unit and a straight wave ‘bar’ or ‘dippers’ which vibrate on the water surface to form waves (double dippers can be used to produce interference patterns). The kit also includes acrylic blocks to allow demonstration of reflection and refraction of waves, or the change in wave velocity with varying depth of water. Levelling feet are included, to ensure the tank can be levelled correctly before use. This simple to assemble kit comes with a link to instructions for assembly and use. Supplied complete with: Shallow tank with detachable legs and feet; frosted screen & projection mirror (to aid demonstrations to a class); single, double & triple point dippers; straight wave dipper bar; acrylic blocks; bright LED light / stroboscope; vibration (wave) generator; control unit with power lead (which varies the wave frequency, strobe frequency, and allows the two to be synchronised).
