Follow repeating motion from one oscillator into traveling waves, sound as a longitudinal wave, pitch-versus-loudness cues, beats from nearby frequencies, Doppler shifts from motion, superposition, standing patterns, and driven resonance.
Use this topic page when you want the wave story to stay tied to the oscillator underneath it. The grouped overview starts with one repeating system, expands into traveling and longitudinal sound waves, separates pitch from loudness on the same compact bench, adds beats as the nearby-frequency superposition bridge on that same sound branch, brings in the motion-caused Doppler shift, and then moves into combined waves, standing patterns, and the driven-response case that explains why resonance matters.
Best first concepts
The topic page keeps these starts in their own compact row so the first screen is about orientation and next action, not stacked feature cards.
See one repeating system from displacement to acceleration and back again, with the math tied directly to the motion on screen.

Follow one traveling wave across the same medium and connect crest spacing, travel delay, source timing, and the relation v = f lambda on one honest live stage.

Related guided tracks
These tracks stay tied to the same shared concept pages and progress model. They are surfaced here either because the authored path meaningfully overlaps this topic page or because the topic catalog marks the track as useful preparation for this branch.
Use oscillation as the entry point, lock down wave speed and wavelength, carry that into longitudinal sound and pitch-versus-loudness cues, add beats as the nearby-frequency superposition bridge, then move into Doppler shifts, interference, standing-wave patterns, and open-vs-closed air-column resonance without losing the live connection between motion and graph.

Specific learning goals
These goal cards stay authored and transparent. They reuse the current topic page, starter tracks, guided collections, concept bundles, and progress cues instead of adding a separate recommendation system on top of this branch.
Start on the topic route, keep the Waves Evidence Loop compact, and reuse the authored wave order before widening into the rest of the branch.

Grouped concept overview
Each group is authored in the topic catalog, but the actual concepts, progress badges, and track cues still come from the canonical concept metadata and shared progress model.
Group 01
Start with the repeating motion itself, then use energy and the circular-model projection to keep the same system readable from multiple angles.
