In what direction does a love wave travel?
A Love wave is a surface wave having a horizontal motion that is transverse (or perpendicular) to the direction the wave is traveling.
What type of motion do primary waves have?
Seismic P waves are also called compressional or longitudinal waves, they compress and expand (oscillate) the ground back and forth in the direction of travel, like sound waves that move back and forth as the waves travel from source to receiver.
What is the motion of secondary waves?
The S-wave (secondary or shear wave) follows more slowly, with a swaying, rolling motion that shakes the ground back and forth perpendicular to the direction of the wave.
What is the direction of secondary waves?
S waves are transverse waves, meaning that the direction of particle motion of a S wave is perpendicular to the direction of wave propagation, and the main restoring force comes from shear stress.
What is PSL wave?
P waves. P waves, or Primary waves, are the first waves to arrive at a seismograph. P waves are the fastest seismic waves and can move through solid, liquid, or gas. They leave behind a trail of compressions and rarefactions on the medium they move through.
What type of wave is Rayleigh 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 type of wave is primary wave?
A P wave (primary wave or pressure wave) is one of the two main types of elastic body waves, called seismic waves in seismology. P waves travel faster than other seismic waves and hence are the first signal from an earthquake to arrive at any affected location or at a seismograph.
What type of waves are secondary waves?
S waves are seismic body waves meaning they travel through the Earth’s interior. Their velocity is slower than that of P waves, and they are normally the second major phase to be observed on a seismogram, and are therefore also referred to as secondary waves.
Are secondary waves transverse or longitudinal?
Body waves travel through the interior of the earth, and have two main types: P-Waves (Primary waves) are Longitudinal Waves. S-Waves (Secondary waves) are Transverse Waves.
What are Love waves and Rayleigh waves?
Two types of surface waves, known as Love waves and Rayleigh waves after their discoverers, propagate near the Earth’s surface. Rayleigh waves result from a combination of P and SV motions, while Love waves result from SH waves trapped near the surface.
What type of wave is P wave?
Primary waves (P-waves) are compressional waves that are longitudinal in nature. P-waves are pressure waves that travel faster than other waves through the earth to arrive at seismograph stations first, hence the name “Primary”.
What kind of wave is perpendicular to the direction of propagation?
Such a wave is called a transverse wave or shear wave; in such a wave, the disturbance is perpendicular to the direction of propagation. In contrast, in a longitudinal wave or compressional wave, the disturbance is parallel to the direction of propagation.
What kind of motion does a love wave have?
Animation by Larry Braile,Purdue University. Love Waves—surface waves that move parallel to the Earth’s surface and perpendicular to the direction of wave propagation. Particle motion consists of alternating transverse motions. Particle motion is horizontal and perpendicular to the direction of propagation (transverse).
What kind of wave has the same direction of travel?
Longitudinal waves have the same direction of vibration as their direction of travel. This means that the movement of the medium is in the same direction as the motion of the wave. Some longitudinal waves are also called compressional waves or compression waves.
How are transverse waves different from longitudinal waves?
A wave can be transverse or longitudinal depending on the direction of its oscillation. Transverse waves occur when a disturbance causes oscillations perpendicular (at right angles) to the propagation (the direction of energy transfer). Longitudinal waves occur when the oscillations are parallel to the direction of propagation.
