MS-334 PVG RIPPLE TANK

RIPPLE TANK

In physics Labs, a ripple tank is a shallow glass tank of water used to demonstrate the basic properties of waves. It is a specialized form of a wave tank.

Demonstrates waves in two dimensions, including such wave phenomena as interference, diffraction (single slit, double slit, etc.), refraction, resonance, phased arrays, and the Doppler effect.

Easy to assemble and packaway. Light weight and stackable.

Simple adjustment of Rippler bar.

Moulded acrylic material, four legs with levelling feet.

High quality plastic tray, light alloy uprights to carry a horizontal adjustable rippler rod,low voltage d.c motor mounted on a wooden beam. Two plastic spheres attached at right angle to beam,

Ripples are usually created by a small electric motor attached to a strip of wood suspended by springs or elastic bands. The motor has an off-centre weight attached so when turned on, makes the strip vibrate and thus create ripples on the surface of the water.

By lighting the waveforms being created, clear peaks and troughs can be seen.

Ripple tanks can be used to show all the basis properties of waves including diffraction, reflection, refraction and interference.

Reflection :Waves can be reflected using pieces of straight or bent metal strip.

Refraction :By a  thick piece of glass or transparent plastic and place it in the path of the plane wave, refraction will take place.

Diffraction :When waves on the sea travel into a harbour with a narrow entrance, they diffract, making a semi-circular pattern when passing through. This can be created using two pieces of metal strip, leaving a gap between the two. The narrower the gap, the more semi-circular the wave will be when it passes through.

Interference :By adding two small balls to the motor assembly, two waves can be created from the point these balls make contact with the water surface.  Identical wave patterns will interfere with each other creating visible light and dark areas where they merge.
