Wave interference

Wave interference occurs when two or more waves overlap in space, and their effects combine to create a new wave pattern that can be either stronger or weaker than the original waves. When the peaks and troughs of waves align perfectly, they amplify each other in what's called constructive interference, while misaligned waves can cancel each other out through destructive interference. This phenomenon explains everyday experiences like why you might hear louder sound in certain spots near speakers or see colorful patterns in soap bubbles.
