The stationary wave have following characteristics
progressive waves traveling in opposite directions along the same line.
⇒ The overall appearance of a standing wave is of alternate intensity maximum (displacement antinode) and minimum (displacement node).
⇒ The distance between adjacent nodes (or antinodes) is λ/2.
⇒ The distance between successive node and antinode is λ/4.
⇒ There is no progressive change of phase from particle to particle.
⇒ All the particles in one loop, between adjacent nodes, vibrate in the same phase, while the particles in adjacent loops are in opposite phase.
⇒ A stationary wave does not propagate in any direction and hence
does not transport energy through the medium.
⇒ In a region where a stationary wave is formed, the particles of the
medíum (except at the nodes) perform SHM of the same period, but the amplitudes of the vibrations vary periodically in space from particle to particle.
