They are seismic waves - those emitted by an earthquake.
P-waves are known as primary waves. They have the fastest velocity of all the seismic waves and so arrive at a seismometer station first. They are a longitudinal or compression wave.
S-waves are secondary waves. They travel more slowly than P-waves, but faster than surface waves so are the second seismic wave to be recorded at a seismometer station. They are transverse or shear waves.
Finally there are the surface waves of which there are two main types. The L-wave or Love Wave and the R-wave or Rayleigh wave. These waves tend to have the largest magnitude and cause the majority of the damage that occurs during an earthquake.

∙ 14y agoa P wave is a primary wave. It is a compression wave, which means the particles of its medium (in this case, the ground) move in the same direction as the energy that is being transferred. (P waves are analagous to "sound waves", since air compresses in order to reach our eardrums) an S wave is the secondary wave. It is a transverse wave, which means the particles of its medium move at right angles to the energy that is being transferred. (S waves are analagous to ocean waves, as the water molecules oscillate only up or down while the wave itself can move many miles from the origin) In the case of Earth's architecture, S waves caused by earthquakes dissipate quickly when reaching the liquid outer core as they are "absorbed" by the liquid's physical properties due to density. An L wave generally refers to any type of surface wave following the P or S wave. More specifically, the term gets its name from AEH Love, who discovered the "Love Wave". However there have been at least one other surface wave discovered since Love's wave (ie: Rayleigh waves)

What are also known as L waves?
Presuming you mean earthquakes, L waves are known as Long waves. P waves are known as primary waves, and S waves are known as secondary waves.
Which wave type is formed when the waves reach the Earths surface?
L waves are formed when P&S waves reach the surface.
What type of seismic wave does not travel through the core?
Primary waves ( P-waves) can travel through earth's outer core.
What does the S wave and P wave stand for?
P waves are primary waves and S waves are called secondary waves
When do P waves arrive at the surface in relation to S waves?
when the P waves arrive at the surface in relation to s waves and surface waves is called the promary waves.
Who are more fastest P S L or W waves?
P waves... L waves are slowest.
What kind of waves are associated with earthquakes?
P waves and S waves also L waves
Waves from an earthquake are know as these?
P or primary wave, S or secondary waves, L as in something waves
Waves from earthquakes are know as these?
P or primary wave, S or secondary waves, L as in something waves
What type of waves are there?
p-wave s-wave l-wave
What are the three seizmic waves?
The 3 seizmic waves are primary or P-wave, secondary or S-wave and surface or L-wave. P-waves expand and compress material. Particles around the wave vibrate and the P-wave is the fastest wave out of the 3. S-waves travel through the ground perpendicular to the forward motion. these waves are slower than P-waves and these waves travel through solids only! L-waves are the most desructive wave. once you know where this guy hits you know where the epicenter of an earthquake is. L-waves are the combination of P- and S-waves.

After an earthquake which type of seismic wave arrives first at a seismometer?
P waves (APEX)
After an earthquake which type of seismic waves reach seismometers last?
A surface wave is the last seismic wave to arrive after an earthquake.
Are P-waves and S-waves transverse or longitudinal waves?
P-waves are longitudinal and S-waves are transverse waves.
What type of seismic wave are P waves and S waves?
P and S waves are body waves.
