Wave Interference Motion

Two overlapping patterns create complex secondary motion waves.

🧐 What do you see?

When the transparency and position of the two grid layers shift against each other, you see a third, much larger wave pattern moving across the screen. This is a dynamic Moiré pattern.

🧠 Why this works

Moiré patterns occur when two repetitive patterns are overlaid with a slight offset or rotation. The visual system groups the intersections of the lines, creating a new, larger-scale pattern (interference fringes).

🧪 Try variations
  • Tilt your head: Even slight changes in viewing angle can alter the perceived speed of the interference pattern.
❓ FAQ

Is this related to physics?

Yes, wave interference is a fundamental concept in physics, explaining phenomena from noise-canceling headphones to light diffraction.
