Sound Propagation Visualizer

CTS anchor: particles oscillate locally while the wave (energy) travels forward through the medium.

Wave direction

Energy travels →

VACUUM: no medium → compressions/rarefactions cannot form → propagation is blocked.

What to observe: the dots do not travel. They pulse in place (local oscillation). The moving highlight represents the compression/rarefaction pattern traveling forward (energy propagation). In a vacuum, propagation is blocked because there is no medium.
