Question

compare progressive and stationary waves​

Answer 1

Answer:

A progressive wave has points of given phase, such as a crest or a dip which travel forwards, whilst the medium remains where it is. ... Standing waves are formed by the superposition of two travelling waves of the same frequency (with the same polarisation and the same amplitude) travelling in opposite directions.

Progressive Waves and Stationary Waves:

1. In a progressive wave, the disturbance travels form one region to the other with definitevelocity. In stationary waves, disturbance remains in the region where it is produced, velocity of the wave is zero.

2. In progressive waves, amplitudes of allparticles are same but in stationary waves, amplitudes of particles are different.

3. In a stationary wave, all the particles cross their mean positions simultaneously but in a progressive wave, this does not happen.

4. In progressive waves, all the particles are moving while in stationary waves particles at the position of nodes are always at rest.

5. Energy is transmitted from one region to another in progressive waves but in stationary waves there is no transfer of energy.
