Wave Interference Lab

Click the canvas to place wave sources and watch real-time interference patterns form.

Destructive (trough)

Node (zero)

Constructive (crest)

Wavelength: 60 px Wave Speed: 1.0× Animate

Sources: 0 / 5

Try these classic setups:

Each source emits circular waves. Where crests meet crests → constructive interference. Where crests meet troughs → destructive interference.

Δr = nλ → constructive

Δr = (n+½)λ → destructive

The double-slit preset recreates Young's double-slit experiment — the key evidence for the wave nature of light.
