Summary

The YGP-6220 sound velocity measurement experimental device drives the ultrasonic transducer through the signal source, so that the ultrasonic wave passes through the air, liquid, solid and other media, and finally is received by the receiving end, thereby measuring the propagation speed of sound waves in these media. The sound velocity measurement experimental device can observe and study the phenomenon of sound wave propagation in different media, and measure the propagation speed of sound waves in different media. The instrument consists of two parts: a special sound velocity test frame and a special signal source, which can be used for basic physics experiments in universities.

The YGP-6220C sound velocity measurement experimental device can also drive a speaker with a sine wave to form a standing wave in a resonance tube, and study the relationship between wavelength and sound velocity by changing the driving frequency and the length of the tube. And based on the closed and open tubes, the concepts of wave nodes, wave antinodes and harmonic waves are studied.

The sound velocity measurement experiment not only covers the two commonly used test methods in basic physics sound velocity experiments, but also can be measured using the time difference method, a sound velocity measurement method actually used in engineering. In the working state of the time difference method, using an oscilloscope, you can clearly and intuitively observe the reverberation waveform generated by multiple reflections and superpositions of sound waves during propagation.
