destructive interference
Waves cancel out
Destructive interference occurs when two waves meet and cancel each other out, either partially or completely.
The peaks of one wave align with the troughs of another, reducing the combined amplitude.
The phenomenon applies to sound, light, water waves, and other wave types.
Noise-canceling headphones work by generating sound waves that destructively interfere with ambient noise.
