Describe how particles of the medium move in a surface wave.

The particles in the medium of a surface wave move neither longitudinal nor transverse, the particles of the medium in a surface waves undergo circular motion.

Explanation:

Surface waves are traveled along the surface of the oceans, these particles undergo circular motion these form ripples on the surface of the water. The motion of the particles in the medium gradually decreases from surface to surface. A surface waves are also called as circular waves as the particles of the medium move in circular direction.
