Question

about sound and vibrations​

Answer 1

• When sound waves move through the air, each air molecule vibrates back and forth, hitting the air molecule next to it, which then also vibrates back and forth. ... They just vibrate back and forth. When the vibrations are fast (high frequency), you hear a high note. When vibrations are slower, you hear a lower note.
