What is the result of destructive interference?

• A. Waves amplify each other
• B. Waves travel in opposite directions
• C. Waves combine to reduce amplitude or cancel
• D. Waves reflect to create new paths

Answer: (C)

Destructive interference occurs when two or more waves overlap and align in such a way that their crests and troughs effectively cancel each other out. This results in a reduction in the overall amplitude of the waves. When waves are perfectly out of phase, meaning that the crest of one wave coincides with the trough of another, they combine to yield a net amplitude of zero, or a significantly reduced amplitude. This phenomenon is commonly observed in various contexts, such as noise-canceling headphones, where sound waves are generated to specifically counter and reduce unwanted ambient noise. In summary, the correct option captures the essence of destructive interference, where the interaction of waves leads to a decrease in amplitude or complete cancellation of the waves involved.
