What happens to ripple on a pond when it hits a large rock?

When ripples on a pond encounter a large rock, they are disrupted and refracted around it. The water's surface changes as the ripples lose their uniform motion, creating turbulence and altering their direction. Depending on the size of the rock and the intensity of the ripples, some energy may be reflected back, while other waves continue to move past the obstacle. This interaction creates a dynamic pattern of movement in the water surrounding the rock.
