Homework Help: Standing waves

  1. Sep 14, 2006 #1
    if a standing wave is a wave which transfers no energy, how is it that a guitar string produces a sound? because it produces it via a standing wave, and the sound is sound energy, so where does the energy come from?

    A standing wave on a string carries no energy from one end of the string to the other.

    It can, and does impart vibration on the air molecules around it, resulting in sound waves.
