i have no idea. You do blah blah blah
The two types of body waves are P-waves (primary waves) and S-waves (secondary waves). P-waves are compressional waves that travel through solids, liquids, and gases, while S-waves are shear waves that only travel through solids.
p waves and s waves
The speed of seismic waves from fastest to slowest is P waves (primary waves), S waves (secondary waves), and then surface waves. L waves are a type of surface wave, so they are generally slower than both P and S waves.
The sub-types of seismic waves are primary (P) waves, secondary (S) waves, and surface waves. P waves are the fastest seismic waves and travel through solids, liquids, and gases. S waves are slower than P waves and only travel through solids. Surface waves are slower than both P and S waves and travel along the Earth's surface.
P-waves reach a seismograph first because they are faster than S-waves. P-waves are compressional waves that can travel through solids, liquids, and gases, whereas S-waves are shear waves that only travel through solids.
