wave interference
Ripples crossing paths
Wave interference is the phenomenon that occurs when two or more waves meet and combine, either reinforcing each other (constructive interference) or canceling each other out (destructive interference).
The concept applies to sound, light, water, and other wave types.
Noise-canceling headphones work by generating sound waves that destructively interfere with ambient noise.
