Interference.
Definition
The phenomenon that occurs when two or more waves overlap in the same space. Constructive interference happens when wave crests align, producing a larger amplitude. Destructive interference occurs when a crest meets a trough, reducing or canceling the wave.
Examples
Real-world.
- 1 Noise-canceling headphones using destructive interference to reduce unwanted sound
- 2 Colorful patterns on soap bubbles caused by thin-film interference of light
- 3 Two speakers producing loud and quiet zones in a room
