Tuning Fork and Oscilloscope

音叉和示波器

The tuning fork sound is picked up by the microphone and displayed on the screen of an oscilloscope. Once the fork has settled down to its fundamental mode, it produces a sine wave trace on the oscilloscope.

调谐叉的声音被麦克风拾取并在示波器的屏幕上显示出来。一旦叉子稳定在基频模式，它会在示波器上产生一个正弦波轨迹。
