Wave labs
Oscilloscope Lab Pick a waveform, raise its pitch, make it louder — and watch the trace change on a real oscilloscope display. Then play "Match the Wave." Resonance Tuner See a standing wave with its nodes and antinodes, count the still points, and tune a string longer/shorter and tighter/looser to hit a target note. Interference Lab Two waves meet — before you look, predict whether they add up, cancel out, or make a slow beat. Then watch the combined wave appear. Doppler Predictor A siren races toward you, a train pulls away — predict whether the pitch sounds higher, lower, or the same. Then see the wavefronts bunch up. Wave at a Boundary A sound, light, or water wave reaches a new material — predict whether it mostly bounces back, passes through, or gets soaked up. Then reveal the energy split.
Practice & play
Mixed Practice A short round across the kits you have played — brought back to make it stick. WaveForge Sprint Race your OWN best on what you already know. Timer optional, no penalty for a miss. Trick Questions Brain-teasers with a twist — spot why the obvious answer is a trap. Teach the Cast Teach a wave idea to a cast member still learning it — teaching makes it stick. Wave Duel 2–4 players take turns on one device — same questions, highest first-try score wins. Wave Journey A progression trail through every kit — clear each stop of real practice, then move on. Progress Your levels, streak, and how each skill area is coming along — saved on this device. Progress report For grown-ups — a private on-device snapshot mapped to the skill areas.
