Well, it's often referred to as the direction of propagation of the wave.
Seismic waves affect us because they are what causes the motion from an earthquake that destroy buildings and such. The three types of seismic waves are surface waves primary waves also called P-waves and secondary waves also called S-waves.
These are called Surface waves
secondary waves.......... i think
another name for pressure wave is a P-wave EDIT: Another name for P-waves or Pressure waves are Compressional, Longitudinal, P, Dilation waves. The particle motion is in the direction of wave propagation These waves occur in Solids, Liquids, and Gases whereas Shear, transverse, S, or equivoluminal waves only occur in solids.
to allow linear or rotary motion in one direction while preventing motion in opposite direction
Such waves are called Longitudinal Waves.
Well, it's often referred to as the direction of propagation of the wave.
amplitude Longitudinal waves occurs when the motion of the medium. This is parallel to the direction of the wave.
amplitude Longitudinal waves occurs when the motion of the medium. This is parallel to the direction of the wave.

amplitude Longitudinal waves occurs when the motion of the medium. This is parallel to the direction of the wave.
Longitudinal waves occur where the motion of the medium is parallel to the waves.
p waves (i think)
transverse waves
perpendicular to or at right angles to their direction of motion
Longitudinal waves occur where the motion of the medium is parallel to the waves.
