:: WAVES, VIBRATIONS AND SOUND
Ripple tank Whether you are dealing with the wave properties of light, electromagnetic waves, sound or other types of waves, their behavior is analogous to the behavior of waves on a water surface. In a teaching situation water waves have the advantage of being visible and moving so slowly that students can observe wave phenomena directly. Exper iment

By taking advantage of the optical properties of water waves, phenomena, can be enlarged and made visible on a screen. The Ripple tank provides a dramatic demonstration of the general properties of waves and propagation phenomena. 1)
Reflection and refraction. By using the linear dipper bar plane parallel waves can be produced. The waves exhibit reflection and refraction when appropriate barriers are used in the water tank.
2)
Inteference phenomena occur when two point source dippers generate circular waves. The distance between the sources and their frequency can be regulated.
3)
Plane parallel waves form point wave sources when they encounter a double slit formed by three barriers.
4)
The propagation velocity is dependent upon the depth of the water layer. The transparent lens cross section is covered by a shallow layer of water.

Projection Intense illumination from the strobe light enables the images to be enlarged and projected using several techniques. On a table it is well-suited for group work e.g. in lab exercises. On a screen it is ideal for classroom demonstrations or lecture halls. 速
