P waves (primary waves) are longitudinal or compressional waves. In solids, these waves generally travel almost twice as fast as S waves and can travel through any type of material. In air, these pressure waves take the form of sound waves, hence they travel at the speed of sound. Typical speeds are 330 m/s in air, 1450 m/s in water and about 5000 m/s in Granite.
S waves (secondary waves) are Transverse_waveversewaves or shear waves, which means that the ground is displaced perpendicularly to the direction of propagation. In the case of horizontally polarized S waves, the ground moves alternately to one side and then the other. S waves can travel only through solids, as fluids (liquids and gases) do not support shear stresses. Their speed is about 60% of that of P waves in a given material. S waves arrive second in a seismic station because of their slower speed.

At what velocity do P-waves travel?
Typical values for P-wave velocities within the Earth are between 5 and 8 km/s.However the velocity is dependent on the elastic properties and density of the material through which the wave is travelling.The P-Wave velocity (VP) can be found using the following:VP = Sqrt((K+ (4/3 x G)) /P)Where:K = Bulk modulusG = Shear modulusP = DensityPlease see the related links for more information.
Which seismic wave type arrives first during an earthquake?
The P Waves. Then the S Waves.
Which travels slower p waves or surface waves?
surface waves because p waves and s waves are way faster so here is how it goes from fastest to slowest: is p wave and then s wave and then surface waves
Is p wave larger s wave surface wave or tsunamis?
Neither. P and S waves are body waves. Tsunamis are a different matter entirely.
What are the three categories of seismic waves?
p wave comes first s wave comes next and last comes surface wave.
Which wave travels farther p-waves or s-waves?
The velocity of s-wave is 60% of p-wave, for a given homogeneous and isotropic medium and a fixed time p-wave would travel farther.
What waves have the highest velocities in earthquakes?
P waves (PRIMARY Waves) have the highest average velocity as they travel through the earth's materials.
At what velocity do P-waves travel?
Typical values for P-wave velocities within the Earth are between 5 and 8 km/s.However the velocity is dependent on the elastic properties and density of the material through which the wave is travelling.The P-Wave velocity (VP) can be found using the following:VP = Sqrt((K+ (4/3 x G)) /P)Where:K = Bulk modulusG = Shear modulusP = DensityPlease see the related links for more information.
compressional wave?
this is the waves of p waves that have same direction of waves
Which seismic wave travels the slowest?
Surface waves, Secondary waves, Primary waves :) I had this as a science question in school a few weeks ago... hope this helps :) Oh whoops i didnt log in so i did it again.... :) :) :) :) :) :) :)
Which waves come first P-waves L-waves or S-waves?
P-waves have the highest velocity so arrive first. Please see the related question for further information on the factors affecting seismic wave velocity.
What are seismic waves that moves rock particles at right angels to the direction of the wave?
P or Primary waves are longitudinal waves that move rock particles back and forth in the same direction that the wave travels.
What type of seismic wave that compresses and expands the ground?
Longitudinal Waves
What does the S wave and P wave stand for?
P waves are primary waves and S waves are called secondary waves
Is a P-wave a seismic wave?
Yes. P-waves are known as primary waves and are a compressional or longitudinal wave.
What are seismic P-waves?
A pressure, or a compressional, wave in which a disturbance vibrates materials back and forth in the same direction as the direction of wave movement.P-waves are also called primary waves, they are a kind of vibration in the Earth's crust, that result from fault movements that cause earthquakes.The P wave is a longitudinal wave or a compressionwave. The force is applied in the direction that the wave is travelling. The ground must move in that direction. Ground or earth is pretty incompressible, so the energy is transferred pretty quickly.
What is a primary wave or p-wave?
Cause rock particles to vibrate in same direction that waves travel
