About WaveForge Play
How it works
WaveForge turns sound and wave physics into things you do — not just facts to memorize.
- Oscilloscope Lab — sound is a wave. Choose its shape (sine, square, sawtooth, or triangle), raise its pitch, and turn up its loudness, and watch the glowing trace change on a real oscilloscope display. Then play Match the Wave: a target trace appears and you tune yours to match it.
- Resonance Tuner — a string only “sings” at its natural frequencies, where it forms a standing wave with still points (nodes) and big-swing points (antinodes). Count the nodes, then make the string longer or shorter and tighter or looser to tune it to a target note.
- Concept kits — 16 short question rounds, from wave basics through sound and music, light, the electromagnetic spectrum, communication technology, and advanced synthesis.
No microphone needed
The iOS app can capture live sound from the microphone. On the web we skip that and draw the waves for you instead, so everything works with no permissions and no recording. A small “Play tone” button can make a sound if you want one — but you can learn everything with the sound off.
Meet the cast
Curve, Meet, Sing, Cruise, and Node each stand for one wave idea — wave basics, interference, resonance, the Doppler shift, and standing waves. You can read their stories and hear them on the cast page.
Our privacy promise
WaveForge Play is free, works offline, and collects nothing. No accounts, no ads, no tracking, and no data ever leaves your device — your level and streak are saved only in this browser.
Mistakes are part of it
You never lose anything for a wrong answer. A wrong guess just points you to the right idea next time — that’s how real experiments work too.
