Explanation
Longitudinal Wave (Primary Nature): Sound propagates as compressions and rarefactions (particles vibrate parallel to wave direction). Example: Sound waves in air. Mechanical Wave (Medium Dependency): Requires a medium (solid, liquid, gas) to travel—cannot propagate in a vacuum. Transverse Wave (In Specific Cases): In solids, sound can also exhibit transverse wave components (particles vibrate perpendicular to the wave direction).
