As we throw a stone, circular waves are generated around the area where the stone hits the surface of the lake. These ripples move outward, and carry the disturbance with them. However, the water does not move with the disturbance. It moves perpendicular to the disturbance, just rising and falling. Such waves are transverse waves- they do not carry the material of the medium with them.

Slowly, the energy of the wave dissipates and the ripples die out.
