Final answer:
In a surface wave, individual particles of the medium move in a circular path as the energy of the wave passes through.
Step-by-step explanation:
A surface wave is a type of wave in which the individual particles of the medium move in a circular path as the energy of the wave passes through. This circular motion is perpendicular to the direction of the wave propagation. Surface waves, like ocean waves or waves on a stretched string, exhibit this type of particle motion.
