What does sound need to travel?

A vibration can cross air or water, but not empty space as sound.

What should you look for?

How did the particles move?

Sound travels when particles in a medium vibrate and pass energy to neighboring particles.

Frequency relates to pitch; amplitude relates to the size of the pressure variation and perceived loudness.

Particle spacing and wave speed are qualitative; volume is capped and starts muted.

Change medium, frequency, and amplitude. Audio is optional and muted at first.
