Quizplus · Accepted Answer

The speed of the water waves in a medium depends on the properties of the medium, such as its density and elasticity, and not on the properties of the object that creates the waves. Therefore, dropping a heavier rock in the water will not affect the speed of the water waves, as long as the properties of the water and the temperature remain the same.
