Equipment set for experiments on geometric and wave-mechanical acoustics.
Based on the piezo-effect discovered by the Curie brothers, an AC voltage is applied to a piezo-electric body causing it to oscillate. Sound waves can also be used to excite the body and the oscillations can be converted into an electrical voltage signal.
Resonant frequency: 40 kHz approx.
Band width: 6 kHz approx.
Capacitance: 1900 pF
Connector: BNC
Stand rod: 150 mm x 10 mm diam.
Dimensions: 40 mm x 20 mm diam.
Contents:
1 Ultrasonic transmitter, on stand rod
1 Ultrasonic receiver, on stand rod
1 Projection screen
1 Ruler, 1 m
