Question

what type of wave is a sound wave? transverse ocean longitudinal

Explanation:

Sound waves are longitudinal waves. In longitudinal waves, the particles of the medium vibrate parallel to the direction of wave propagation. For sound, air molecules (in the case of sound traveling through air) move back - and - forth in the same direction that the sound wave is moving. Transverse waves have particle vibration perpendicular to the wave direction (e.g., light waves in vacuum, or waves on a string). "Ocean" is not a type of wave classification in terms of wave mechanics (ocean waves are a complex combination of different wave types in a fluid medium but not a fundamental wave type like transverse or longitudinal).

Answer:

longitudinal
