Wave Interference Visualiser

Two wave sources, one pattern: explore constructive and destructive interference and reveal the nodal lines in this animated visualiser.

Wave Interference Visualiser

Two sources send out circular waves. Where crests meet crests the waves add up; where a crest meets a trough they cancel out.

What the bands mean: bright bands are constructive interference (waves in step, bigger amplitude); dark bands are destructive interference (waves out of step, cancelling out).
