Gravity waves and ripples : the speed of a wave through a liquid depends on gravity and surface tension. If some portion of a liquid is forced upwards and downwards ; the gravity acts to bring the displaced portion to their undisplaced portion. That is gravity provides the necessary resorting forces required for motion of waves. But the formation of waves causes the surface of water to become curved. And surface tension tend to float the surface. For long waves the curvature of displaced portion is small. For this, some wave are chiefly propagate by gravity. , and are called gravity waves. However if waves are short, some waves are chiefly propagate by surface tension, called ripples.
