In 3-4 sentences, explain seismic wave types. State any key formula.

# Seismic Wave Types Seismic waves are vibrations that travel through Earth, classified into **body waves** (P-waves and S-waves) and **surface waves** (Love and Rayleigh waves). **P-waves** (primary) are compressional waves that travel fastest and can move through solids, liquids, and gases, while **S-waves** (secondary) are shear waves that travel slower and only through solids. **Surface waves** travel along Earth's surface and cause the most damage during earthquakes, with Love waves moving horizontally and Rayleigh waves creating rolling motions. **Key formula:** Wave velocity v = √(E/ρ), where E is the elastic modulus and ρ is density. For P-waves specifically: v_p = √[(K + 4μ/3)/ρ], where K is bulk modulus and μ is shear modulus.
