Wave phenomena in a ripple tank

Product No: P2133400

Principle

In the ripple tank water waves are generated by a vibration generator. Circular waves are then used to investigate the dependency of the vibration frequency on the wavelength. With the aid of plane waves the dependency of the velocity of the waves' propagation on the depth of the water can be determined. Moreover, the reflection of waves as well as the refraction of waves at a plate, a prism, a concave lens and at a convex lens can be clearly demonstrated. It is shown, that water waves are a proved method to demonstrate the behaviour of waves in general.

Tasks

Use the single dipper to generate circular waves. By using a ruler the wave length can be determined. The measurement is made for different frequencies.
The external wave generator is connected to the water ripple tank and circular waves are generated. By moving the external wave generator the Doppler Effect is investigated.
Plane waves are generated with the integrated wave generator. By using two barriers show the reflection of waves.
Use a plate to simulate a zone of lower water depth and measure the wave length before and above the plate.
Observe the refraction of water waves at several objects (plate, prism, concave and convex lens).
