INSTRUCTION SHEETFig 1 Fig. 2Fig. 1 shows ripple generator clamped to the support rod (looking from the top). Thegenerator can clamp to the rod also at 90 0 around.Fig. 2 shows ripple tank assembly with ripple generator mounted on its support rod. Note thetwo cams protruding from the side plates. These cams can be rotated relevant to one anotherto set the phase between them.Fig. 3 Fig. 4Fig.3 shows a ripple tank assembly with the Illuminator attached to its support frame by therubber ring. It is positioned approximately over the centre of the tank. The Illuminatorconnects to any 12V.AC/DC power source and the images are viewed on the flat white screenwhich is positioned on the table under the ripple tank.Fig 4 shows the rays of light passing through the waves which behave like lenses. This effectcauses a focussing of the light on each wave and bright and dark bands of light are seen onthe white screen.NOTE: Shallow water always provides a better image resolution than deep water.INDUSTRIAL EQUIPMENT & CONTROL PTY.LTD.6 1 - 6 5 M c C l u r e S t .

INSTRUCTION SHEETFig.5 Fig. 6Figs. 5 & 6 show that shallow water provides a greater proportional variation in water depththan deep water. Therefore shallow water provides better images than deep water. For bestresults, keep the water depth in the ripple tank to a practical minimum.Fig. 7 Fig. 8Fig. 7 shows that for REFRACTION experiments, there must be a very large difference inwater depth. Also lower frequency waves give better results than higher frequencies. Whena thick glass slab (not supplied in standard kit) is placed into the tank to create a largedifference in water depth, be sure the water is just covering the glass.Fig. 8 shows the straight aluminium rippler with the thin edge downwards for thin straightripples and with the folded thick edge downwards for large ripples.Fig. 9 Fig. 10Fig. 9 shows the ripple generator and its speed adjustment knob fitted with a straight sheetrippler with one or more point source tips fitted. All point sources dip into the water at thesame time to create a multiple point source.Fig. 10 shows ripple generator and its speed adjustment knob with a separate point sourcefitted to opposite side plates to permit the adjustment of phase between them. This providestwo point sources with adjustable phase.INDUSTRIAL EQUIPMENT & CONTROL PTY.LTD.6 1 - 6 5 M c C l u r e S t . T h o r n b u r y . 3 0 7 1 M e l b o u r n e .
