Wave Interference — Free Online Wave Superposition Physics Game
Wave Interference renders a live 2D interference field in real time — every pixel shows the superposition of your wave sources. Drag sources to reshape the pattern and hit constructive or destructive interference targets across 8 levels of increasing complexity.
The physics behind the game
Wave superposition
Every point in space receives contributions from all sources simultaneously. The amplitudes simply add — this is the principle of superposition, valid for all linear waves.
Constructive interference
When two waves arrive with path lengths differing by a whole number of wavelengths, their crests and troughs align — amplitude doubles.
Destructive interference
When path lengths differ by a half-wavelength, crests meet troughs — the waves cancel. This is the principle behind noise-cancelling headphones.
Standing waves
Two waves of equal frequency travelling in opposite directions create a standing wave — nodes (zero amplitude) and antinodes (maximum amplitude) fixed in space.
