Question

Quizplus · Accepted Answer

S waves are also known as shear waves because they travel by causing particles in the medium to move perpendicular to the direction of wave propagation. This is in contrast to P waves, which are also known as compression waves because they travel by causing particles in the medium to move parallel to the direction of wave propagation.
