What type of waves makes a material particle oscillate in an elliptic path in the vertical plane?

Rayleigh wave makes a material particle oscillate in an elliptic path in the vertical plane (with horizontal motion along direction of energy transmission). P-waves are fastest, followed in sequence by S-, Love and Rayleigh waves.

What seismic waves move in elliptical?

Rayleigh Waves—surface waves that move in an elliptical motion, producing both a vertical and horizontal component of motion in the direction of wave propagation.

Which waves cause a particle motion that is back and forth in a direction parallel to the wave motion?

Explain that earthquake waves move particles of material in different ways: whereas, compressional waves create a back and forth motion parallel to the direction of the waves, shear waves create a back and forth motion perpendicular to the direction of the waves. 4.

What is elliptical in vertical plane?

A type of surface wave in which particles move in an elliptical path within the vertical plane containing the direction of wave propagation. At the top of the elliptical path, particles travel opposite to the direction of propagation, and at the bottom of the path they travel in the direction of propagation.

What are the seismic waves?

A seismic wave is an elastic wave generated by an impulse such as an earthquake or an explosion. Seismic waves may travel either along or near the earth’s surface (Rayleigh and Love waves) or through the earth’s interior (P and S waves).

What are seismic waves types?

There are three basic types of seismic waves – P-waves, S-waves and surface waves. P-waves and S-waves are sometimes collectively called body waves.

Which seismic waves cause a circular particle motion?

Rayleigh waves move in a circular pattern with the crest (highest point) moving up and forward and the trough (lowest point) moving down and backwards. Surface waves attenuate where they are strongest near the epicenter and dissipate as you move farther away.

What type of wave is a Rayleigh wave?

surface wave
Rayleigh waves are a type of surface wave that travel near the surface of solids. Rayleigh waves include both longitudinal and transverse motions that decrease exponentially in amplitude as distance from the surface increases.

What are seismic waves made of?

Seismic waves are waves of energy that travel through Earth’s layers, and are a result of earthquakes, volcanic eruptions, magma movement, large landslides and large man-made explosions that give out low-frequency acoustic energy.

What is a seismic wave and what are its types?

Types of Seismic Waves The two main types of waves are body waves and surface waves. Body waves can travel through the Earth’s inner layers, but surface waves can only move along the surface of the planet like ripples on water. Earthquakes send out seismic energy as both body and surface waves.

What is a type of seismic wave that has a particle motion of left and right?

There are two types of surface waves. Like body waves, they are characterized by particle motion. In the near surface, this motion is “retrograde”, meaning that it is counter-clockwise when the propagation is left-to-right. At depth, the motion can reverse to prograde.

What are the types of seismic wave?

There are two broad classes of seismic waves: body waves and surface waves. Body waves travel within the body of Earth. They include P, or primary, waves and S, or secondary, waves. P waves cause the ground to compress and expand, that is, to move back and forth, in the direction of travel.
