Wave interference occurs when two or more waves meet and combine their effects. This can happen with various types of waves, such as sound waves, light waves, or water waves. When waves overlap, they can either amplify each other, resulting in a stronger wave, or cancel each other out, leading to a weaker wave. This phenomenon is known as constructive and destructive interference, respectively. In everyday life, wave interference can be observed in many situations. For example, when two people speak at the same time, their voices may blend together, creating a complex sound. Similarly, in water, when two stones are thrown into a pond, the ripples can interact, creating patterns of waves that demonstrate interference.
