Answer
In a surface wave (such as a water wave), particles like water molecule undergoes circular motion.
Step-by-step explanation:
surface waves are the waves which does not possess transverse or longitudinal nature. In surface waves (water waves) all the particles of the bulk medium(water) does not moves in perpendicular direction or in parallel direction with respect to energy transport direction. In surface wave only surface particles moves in circular motion.
For example when we through a stone in water that time only surface particles moves in circular direction and it creates ripples.
