1. Description

The water wave channel serves for the demonstra-

tion and investigation of surface waves in water.

It consists of a large transparent oblong trough,

which is two-thirds filled with water.

The waves are produced in the short V-shaped

section and studied in the I-shaped section. For the

generation of the waves a motor with transmission

is attached at the end of the V-shaped channel. It

propels two wave exciters, which move up and

down in the water. Each exciter produces a wave in

a section of the V-shaped channel. Depending

upon the setting, the two exciters can move in the

same direction or in contra motion. The frequency

of these waves can be varied by changing the oper-

ating voltage of the motor.

In both partial channels there is a frame with a

fleece directly in front of the wave exciters which

the waves must pass through. Thus to a large ex-

tent a sinusoidal process is achieved. Then the

waves enter the I-shaped part of the channel and

move along to its end. If the absorbing frame with

fleece is introduced at the end of this channel,

then they are dissipated as far as possible. Thus a

continuous wave pattern develops in the channel.

If the absorber is not inserted, the waves travel to

the end of the I-shaped channel and are reflected.

With a short switch-on time of the motor, a wave

train develops which travels through the channel

and is reflected and travels back towards the ex-

citer. With continuous operation of the motor the

arriving and the reflected waves overlap, producing

an image of a motionless standing wave.
