This compact unit from Lascells provides an elegant method of demonstrating the wave phenomena 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
