*plane pressure pulse wave*
.
*also known as “1 waves”*
.
*’longitudinal waves’ are ‘wave/s’ in which the ‘dis-placement of the medium is in the same direction as, or the opposite direction to, the direction of travel of the wave*
.
Mechanical longitudinal waves are also called compressional waves or compression waves, because they produce compression and rarefaction when traveling through a medium, and pressure waves, because they produce increases and decreases in pressure.
The other main type of wave is the transverse wave, in which the displacements of the medium are at right angles to the direction of propagation.
(some transverse waves are mechanical, meaning that the wave needs a medium to travel through)
.
(‘transverse mechanical waves’ are also called “t-waves” or “shear waves”)
