Learn how overlapping waves can lead to constructive interference, forming amplified waves, or destructive interference, resulting in cancelled waves. Uncover the significance of phase shifts and path length differences in shaping wave behavior.

Destructive interference happens when two waves overlap in such a way that they cancel each other out. Wave interference also depends on the relative phase of the two waves, as this video shows through the examples of path length differences and pi shifts.
