Question

S waves are also known as

Answer 1

Answer:

In physics, a transverse wave is a moving wave whose oscillations are perpendicular to the direction of the wave or path of propagation. ... In seismology, shear waves are also called secondary waves or S-waves.

Explanation:

For seismic waves through the bulk material the longitudinal or compressional waves are called P waves (for "primary" waves) whereas the transverse waves are callled S waves ("secondary" waves). ... S waves are transverse waves which involve movement of the ground perpendicular to the velocity of propagation.

Answer 2

Explanation:

In seismology, S-waves, secondary waves, or shear waves (sometimes called elastic S-waves) are a type of elastic wave and are one of the two main types of elastic body waves, so named because they move through the body of an object, unlike surface waves.
