Earthquake Waves and Their Properties
Waves generated by an earthquake are classified into two main types: P-waves and S-waves. P-waves are longitudinal and can travel through both solids and fluids. S-waves are transverse and can only propagate through solid materials. The reflections and refractions of these waves provide valuable information about the Earth’s interior.
Understanding Longitudinal Waves
The wavelength of a longitudinal wave is the distance between successive compressions or rarefactions.
