# interference
Interference is what happens when two or more waves meet: crests can stack into something bigger, or cancel out entirely. This tag brings together every simulation built around that idea, across water, sound and light. Ripple Tank and Water Ripples show the effect at its most literal, with overlapping circular waves on a water surface, while Wave Interference and Wave Packet Interference generalise it to abstract wave sources. Diffraction & Interference and the Fabry-Pérot Interferometer move into optics, showing how light bends around edges and bounces between mirrors to build sharp interference fringes, and Holography and Holography Concept explain how interference patterns can record a full 3D image. Beat Frequency demonstrates the same principle in sound as two close pitches pulse against each other, and Noise Cancellation shows interference used deliberately, to cancel unwanted sound rather than create a pattern.

🌊 Facts about this collection
- 12 simulations are tagged interference — the second-largest of the nine tags in this batch.
- Two pairs cover the same phenomenon at different depths: Ripple Tank / Water Ripples for surface waves, and Holography / Holography Concept for recorded interference patterns.
- EM Wave Simulator (FDTD) is the only entry that solves Maxwell's equations directly on a grid rather than approximating wave behaviour.
- Beat Frequency and Noise Cancellation are the two audio examples, showing interference reinforcing and cancelling sound respectively.
