Why standing waves are called standing?

  • physics -

    Because the peaks and valleys of wave motion do not move. Only the vibrating medium moves, at the frequency of the wave.

    Standing waves are caused by a pair of matched (amplitude/frequency) travelling waves moving in opposite directions.

    I will try to find a website with an illustration or video of what is meant
