Here's why:
* Compressional waves are waves where the particles in the medium vibrate parallel to the direction of wave propagation. This means the particles oscillate back and forth in the same direction that the wave is traveling.
* Transverse waves are the ones where the particles move perpendicular to the direction of wave propagation. Think of a wave on a string or a water wave.
Examples of compressional waves:
* Sound waves: Sound travels as compressions and rarefactions (expansions) of air molecules.
* Seismic P-waves: These are the fastest type of seismic waves and travel through solids, liquids, and gases.
