Interference refers to the phenomenon that occurs when two or more waves overlap and combine to form a new wave pattern. This can happen with various types of waves, including sound waves and light waves. The result can be constructive interference, where the waves amplify each other, or destructive interference, where they cancel each other out. In everyday life, interference can be observed in various contexts, such as the colorful patterns seen in soap bubbles or the way sound can become louder or softer in different locations. Understanding interference is crucial in fields like acoustics and optics, as it helps explain many natural and technological processes.
