1. progressive wave is an advancing wave which propagates the medium continuously with finite velocity while in case of stationary wave , there is no advancement of the wave in any directions.
2. progressive waves are produced due to continuous periodic vibrations of the particles of a portion of a medium while stationary waves are produced due to superposition of two identical progressive waves moving along the same line but in opposite directions in a medium.
3. in case of progressive, amplitude of each particles is same while in case of stationary wave amplitude varies point to point.
4. progressice wave curve advances without change of shape while stationary wave curve change its shape time to time . it shrinks to straight line twice in each period.
