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.
P-waves and primary waves are the same thing. They may also be known as pressure waves (or compression waves) due to their mode of propagation, the way they move through the Earth.
Compression Waves
l waves are the slowest our waves . They are also called "Long Waves" . They travel along the surface of the Earth . They are the ones that people notice the most .
L waves, also known as Love waves, are a type of surface wave that move in a horizontal, side-to-side motion. They travel along the Earth's outer layer and can cause significant shaking and damage during earthquakes due to their long wavelengths and high amplitudes. L waves move slower than P and S waves but are responsible for the most long-lasting and destructive effects of an earthquake.
Surface waves, also known as Love and Rayleigh waves, do not travel through the core of the Earth. These waves move along the surface of the Earth and are responsible for the most destruction during an earthquake.
Surface waves
L waves
L waves, also known as Love waves, are a type of surface wave that travel through the solid layer of the Earth's crust. These waves move by shaking the ground side-to-side in a horizontal direction. L waves are slower than other seismic waves but can cause significant damage during earthquakes.
P-waves and primary waves are the same thing. They may also be known as pressure waves (or compression waves) due to their mode of propagation, the way they move through the Earth.

P-waves and S-waves. P waves are known as Primary waves as they have a high velocity and so are recorded at seismometer stations before Secondary or S-waves. P waves may also be known as pressure waves as they are in fact compression or longitudinal waves. S-waves may also be known as shear waves as they are transverse waves.
there are 3 types of shock waves produced by an earthquake:the P waves which is known as the (primary or compression) waves are the first to arrive at the recording station, p waves are formed when matter in the rocks is pushed together by the earth's movement. they can travel through solids and liquids.the S waves which is known as the (secondary )waves are the second waves to arrive at the recording station. this waves are also called the shear waves. these waves are formed by the sideways motion of matter, it can only travel through solids.BSecondary waves are also known as shear waves and primary waves are also known as pressure waves.
L waves, also known as Love waves, are a type of surface wave that move in a horizontal, side-to-side motion. They travel along the Earth's outer layer and can cause significant shaking and damage during earthquakes due to their long wavelengths and high amplitudes. L waves move slower than P and S waves but are responsible for the most long-lasting and destructive effects of an earthquake.
The L- Wave or the Love and Rayleigh waves (collectively known as surface waves) cause most of the damage during an earthquake.
P waves... L waves are slowest.
