Water Wave Channel
A wave trough used for demonstrating and investigating the basic properties of waves, using waves in water as an example.
The Water Wave Channel generates sinusoidal waves within its long, plexiglas duct, and the frequency and wavelength of this movement can be varied continuously. The unit is also able to generate non-periodic waves when a pulsed input is applied.
This device can be used to aid a number of experiment topics, including excitement of periodic and non-periodic wave-forms, and deflection, phase and amplitude. It therefore makes a great addition to any classroom lab.
How Does the Water Wave Channel Work?
The plexiglas duct is filled with water and a sinusoidal wave is generated. This propagates with no reflection at the end thanks to an absorber mechanism. The frequency, and thus the wavelength, of the resulting movement can be varied continuously.
In order to investigate reflection, the absorber at the end can be removed. Two exciting mechanisms are supplied that can be operated in or out of phase, whilst the waves that they generate can be viewed separately or superimposed.
By applying a pulsed input to the exciters, non-periodic waves can be generated.
