Phase & sign — quick reference
Oscillation: y = A·sin(ωt + φ) — φ sets the head start. +φ leads, −φ lags.
Travelling wave: y = A·sin(kx − ωt) moves in +x; kx + ωt moves in −x.
Relations: ω = 2πf, k = 2π/λ, v = ω/k = fλ.
Particle velocity ∂y/∂t ≠ wave velocity v. A crest is where phase = π/2.

Waves & Oscillations

Every oscillation is a live trace on the bench. Drag the amplitude, watch the phasor spin, pluck the string — and hear the physics.

◈ The Lab
Six live benches — drag the phasor, pluck a string, overlay two tones and hear the beat, watch the Doppler wavefronts bunch. Every module is a hands-on instrument with live readouts and real audio.
