What type of wave is sound?

Explanation:
Sound is a longitudinal mechanical wave. In air and other fluids, particles oscillate back and forth in the same direction as the wave travels, creating compressions and rarefactions that move through the medium. Because it relies on matter to transmit these pressure changes, sound cannot travel through a vacuum. It is not an electromagnetic wave, which propagates via changing electric and magnetic fields and can travel without a medium. A transverse wave has particle motion perpendicular to the direction of travel, which is not how sound moves in air. So the correct description is a longitudinal mechanical wave.
