Answer:
Stationary Waves
Progresssive Waves
(i) The disturbance remains confined to a particular region, and there is no onward motion.
The disturbance travels forward, being handed over from one particle to the neighbouring particle.
(ii) There is no transfer of energy in the medium.
Energy is transferred in the medium along the waves.
(iii) The amplitude of vibration of particles varies from zero at nodes to maximum at antinodes.
The amplitude of vibration of each particle is same.
(iv) The particles of the medium at nodes are permanently at rest.
No particle of the medium is permanently at rest.
