Wave Interference
Interactive simulation — adjust parameters and watch the visualization update in real time.
How it works
Two coherent point sources in a square ripple tank (top view). The field is the sum of two outgoing circular waves; interference creates quasi-hyperbolic nodal lines and curved maxima. Toggle decay to mimic cylindrical spreading.
Key equations
η = A₁ sin(kr₁ − ωt) + A₂ sin(kr₂ − ωt)
Path difference Δr = r₂ − r₁: constructive when kΔr ≈ 2πn, destructive near kΔr ≈ (2n+1)π (same amplitude).
