What type of wave includes particles moving in a circular motion?

The type of wave that includes particles moving in a circular motion is a surface wave. Surface waves occur at the interface between two different mediums, such as water and air. Due to the gravitational forces acting on the particles, they move in circular or elliptical paths as the wave passes. A common example of surface waves is found in water waves, where the motion of water molecules exhibits this circular movement, contributing to both the upward and downward motion of the surface.

Transverse waves involve particle motion that is perpendicular to the direction of energy propagation, which would not result in circular motion. Longitudinal waves consist of particles moving back and forth in the same direction as the wave travels. Electromagnetic waves are a form of transverse wave that does not involve particle motion since they consist of oscillating electric and magnetic fields moving through space. Thus, the specific characteristic of circular particle motion is unique to surface waves.
