Here's why:
* Longitudinal waves involve the particles of the medium vibrating parallel to the direction of the wave's propagation. This creates areas of compression (where the particles are close together) and rarefaction (where the particles are spread out).
* Transverse waves, on the other hand, have particles vibrating perpendicular to the direction of wave travel. Think of a wave on a string or water ripples - the particles move up and down, while the wave moves horizontally.
Examples of Longitudinal Waves:
* Sound waves: Sound travels through air, water, or solids as a series of compressions and rarefactions.
* Seismic P-waves: These are the fastest type of seismic waves and travel through the Earth's interior as longitudinal waves.
