Item no.: P2151915
Ultrasonic waves of the same frequency, amplitude and direction of propagation are generated by two sources of sound positioned parallel to each other. The sources can vibrate both in-phase and out of-phase. The angular distribution of the intensity of the waves, which interfere with each other, is automatically recorded using a motor-driven, swivel ultrasound detector and a PC.
- Determine the angular distribution of two sources of ultrasound vibrating in phase.
- Determine the angular positions of the interference minima and compare the values found with those theoretically expected.
- Repeat the measurements with the two sources of ultrasound vibrating out of-phase.
