A progressive wave is a term given to a wave that travels from a specific point A in the medium to another point B. In simple terms, a wave that continuously travels in a medium in the same direction minus the changes is known as a traveling wave or progressive wave. Furthermore, a progressive wave is of two types; namely, transverse wave and longitudinal wave.

Transverse Waves:

These are waves in which the particle displacement in the medium is measured perpendicular to the wave direction or direction of wave travel. Longitudinal Waves: With Longitudinal Waves, the particle displacement remains in the same direction to the wave travel.

Plane Progressive Harmonic

Wave During the transmission of a wave via a medium, the particles present in the medium tend to vibrate harmonically about their mean positions; in this case, the wave is tagged as a plane progressive harmonic wave. Simple Harmonic Progressive Wave This waveform continuously travels in a specific direction without any transition in form. Furthermore, the particles of the medium tend to move harmonically about their mean position carrying the same amplitude and period.
