Description:
This advanced ripple tank comes complete with all accessories needed for wave investigations.
Tank is intensely illuminated by a strong light source, and synchronized with the wave generator to help students observe the wave patterns on a workgroup table. The frame is made of reinforced plastic and with foam beaches (to negate reflections). Includes a mirror, which can be mounted at 45 degrees, to project the ripples onto a translucent screen on one side of the unit. Each water wave acts much like a curved lens. The crest of the wave is seen as a bright region and the trough is seen as a dark region. Inside the ripple tank is a mechanical vibrator attached to a wave generator that produces either point wavelets or parallel wave fronts. Various obstructions and barriers can be inserted into the path of the wave, such as a single slit, a double slit, or an edge. Comes complete with all accessories needed for wave investigations Intensely illuminated for effective student observations Built in projection screen Reinforced frame with foam beaches Set includes:
