Here's why:
* Longitudinal waves involve the particles of the medium vibrating parallel to the direction the wave travels. Think of a spring: when you compress a section, the compression travels down the spring as a wave. The individual coils of the spring move back and forth (longitudinally) as the wave passes.
* Transverse waves have particles vibrating perpendicular to the direction of wave travel. Imagine a rope tied to a post: if you shake the rope up and down, a wave travels along the rope. The rope particles move up and down (transversely) while the wave itself moves horizontally.
Examples of longitudinal waves:
* Sound waves: Sound travels through air, water, and solids as compressions and rarefactions (areas of high and low pressure) that move parallel to the direction of the wave.
* Seismic P-waves: These are primary waves generated by earthquakes that travel through the Earth's interior as compressions and expansions.
