Detailed Solution

Sound travels in longitudinal waves, and its speed is determined by the medium through which it travels. As a result, the speed of sound varies depending on the medium. Because of the density difference between water and air, the value of the speed of sound in water differs from the value of the speed of sound in air. As a result, as the medium becomes denser, the speed of sound increases, which is why the speed of sound in water is greater than the speed of water in air.

At room temperature, the speed of sound in water is approximately 1500 m/s. The speed of sound will always be in this range at all temperatures.
