About this app
Explore how two traveling waves add together. The blue and red waves are the originals, and the yellow wave shows their sum. Adjust each wave's amplitude, wavelength, and direction, or drag it to shift its phase. Hold the 'Simulate' button to watch constructive and destructive interference unfold over time. Send matching waves in opposite directions to create a standing wave with fixed nodes and antinodes, or use slightly different wavelengths to produce a beat pattern.
