Standing or stationary wave results when two
progressive waves of same wavelength and
amplitude travelling with same speed in opposite directions superpose.
Characteristics:
-
Energy is not transferred from particle to particle
-
Amplitude of vibration of particles is maximum at antinode and minimum (say zero) at nodes.
-
Time period of all particles is same except at nodes.
-
Wavelength and frequency of standing wave is
same as that of the component wave. -
Pressure variation is minimum at antinode and
maximum at nodes.
