Write some characteristic of the stationary wave.

Characteristics of stationary waves:

(i) The disturbance is confined to a particular region between the starting point and the reflecting point of the wave. 

(ii) There is no onward motion of the disturbance from one particle to the adjoining particle and so on beyond this particular region.
(iii) The total energy assosciated with a stationary wave is twice the energy of each of the incident and the reflected wave. There is no flow of energy along the stationary waves.

(iv) In a stationary wave, the medium splits up into a numvber of segments. Each segment is vibrating up and down as a whole. All the particles in one particular segment vibrate in the same phase. 
(v) There are certain points in the medium of standing wave, which is permanently at rest. These are called nodes. And certain other points in the medium where the amplitude is maximumwhich are called antinodes.
