(1) Standing pulse can be longitudinal / transverse.
(2) The disturbance confined to a particular part among the starting point and reflecting point of the ray.
(3) There is no forward speed of the disturbance from single molecule to the adjoining particle and so on, beyond this ceratin section.
(4) The total energy related with a stationary wave is twice the power of every of incident and reflected pulse. As in stationary pulse nodes are permanently at rest. So no power can be transmitted across then i.e. power of single part is confined in that section. Though this energy oscillates among kinetic energy and elastic potential energy of molecules of the medium.
