RING AND BALL ON STAND
RIPPLE TANK
PHY-00614
Ripple tank is a device to illustrate the laws of wave phenomenon-using ripples on the surface of water as the prototypes of all transverse waves. Ripple tank illustrates important wave motions like rectilinear and circular. It can also demonstrate refraction, diffraction and interference of water waves. Tank is supported by four legs having leveling screws. supplied complete with ripple assembly, two straight obstacles , one straight obstacle , curved reflector, transparent refraction plate, wooden wave roller, one pack of rubber bands, water dropper, sponge, illuminator, electrically operated.
RIPPLE TANK LED ILLUMINATION
PHY-00612
This compact unit provides an elegant method of demonstrating the wave phenomenaof reflection, diffraction, refraction and interference with none of the setting-up problemsusually associated with ripple tanks. The concept has been developed to offer newfeatures in this design. A 10cm tank on a base unit provides the wave generatorand light source to project wave images on to the translucent screen which can then beviewed from above. The LED light source has been upgraded to give super-brightimages and can now be controlled independently of the wave generator. Three settingsgive light ON, SYNC and FREE. Sync has wave frequency synchronized to lightfrequency to give perfectly stationary images. Free gives independent control of thelight frequency to give slowly moving images. Supplied with a full set of interchangeable dippers, barriers, refraction plates and plug top power unit.
RISING TABLE
PHY-00615
For determining the surface tension of liquid by capillary rise method The apparatus comprise metal frame, on which four capillary tubes of 10cm. long and of different internal diameters are clamped with the help of small metal brackets. The 9 mm. rod is also attached to metal plate, so that complete clamp can be held in any stand. Consisting a cast aluminium 100 mm dia table with adjustable stand.
