Kit Benefits:
– The resonant tube makes it easy to experiment with sounds.
– A loudspeaker connected to an audio frequency generator reproduces a sound wave of a given frequency.
– Equipped with a sound level meter (noise meter) to monitor the position of the wave node and the beam in the resonant state.
– By connecting a microphone to an oscilloscope you can determine the wave pattern.
– This instrument is used to detect a sound wave in both an open and closed tube, and to observe a stationary sound wave inside the tube using an oscilloscope.
