After opening the page, a full-screen wave animation will be displayed. Multiple wave sources emit circular waves at the same time. When the waves meet, interference will occur-the place where the peaks overlap is brighter, and the place where the peaks and troughs meet is offset and darkened. The color changes dynamically based on the height of the wave.

The whole process is pure front-end animation. Based on Canvas, the wave height superposition value of each point is calculated pixel by pixel, which consumes a lot of performance but the effect is realistic. The number of wave sources, wavelength, amplitude, etc. can be adjusted through parameters.

Suitable for use as background animations for meditation and relaxation, physics teaching demonstrations, or purely appreciating the beauty of waves. The implementation principle is the superposition of classic wave equations, with a code of about 300 lines.

Wave Laboratory is a real-time wave interference animation special effect based on Canvas that simulates the superposition and interference effects of wave phenomena such as water waves and sound waves.
