Here's why:
* Longitudinal waves involve particles oscillating back and forth in the same direction as the wave is traveling. Imagine a spring: if you push one end, the compression (and the energy) travels down the spring. The individual coils of the spring move back and forth along the direction of the wave.
* Transverse waves, on the other hand, have particles oscillating perpendicular to the direction of wave travel. Think of a wave in a rope: the rope moves up and down (perpendicular) while the wave travels horizontally.
Examples of longitudinal waves:
* Sound waves: These waves travel through air, water, or solids by compressing and expanding the medium.
* Seismic P-waves: These are the first waves to arrive during an earthquake, and they travel through the Earth's interior by compressing and expanding the rock.
