A wave in which the positions of nodes
(positions of zero vibration) and antinodes
(positions of maximum vibration) do not move.
Standing waves result when two similar waves
travel in opposite directions through the
same space. For example, when a sound wave is
reflected back along its own path, as when a
stretched string is plucked, a standing wave
is formed. In this case the antinode remains
fixed at the centre and the nodes are at the
two ends. Water and electromagnetic waves can
form standing waves in the same way.
