What term describes a standing wave in which there is no net transfer of energy?

• A. Standing Wave
• B. Traveling Wave
• C. Stochastic Wave
• D. Stationary Wave

Answer: (A)

A standing wave is a wave pattern that does not transport energy along the medium. It forms when two waves of the same frequency and amplitude travel in opposite directions and interfere, creating fixed nodes where there is no motion and antinodes where the motion is maximal. Even though the medium at each point oscillates, energy sloshes back and forth between kinetic and potential forms locally, and the time-averaged energy flow along the string is zero. This lack of net energy transfer distinguishes it from a traveling wave, which carries energy along the medium. Stationary wave is sometimes used synonymously, but standing wave is the standard term for a pattern with no net energy transport.
