"Wave that moves in a medium."
Progressive (Traveling) Waves:
A wave, which travels (moves) from one point to another point in a medium.
All particle which are in motion are in same amplitude and frequency but phase of the vibration ranges point to point along the waves. No particles are permanently at rest but they vibrate with different phase.
Progressive wave
Both Transverse wave and Longitudinal waves are Progressive wave.

Stationary (Standing) Waves:
A wave, that remains in a constant position. This is because, the medium is moving in the opposite direction to the wave (i.e. two progressive waves of same amplitude and frequency travel with the same speed in opposite direction to each other).

In stationary wave, there are some points which are permanently at rest, as shown above. The fixed (rest) points are called nodes.
