How much faster does sound travel in water compared to air?

Sound travels significantly faster in water than in air due to differences in density and elasticity between the two mediums. In air, sound waves travel at approximately 343 meters per second, while in water, the speed increases to about 1,480 meters per second. This means that sound travels roughly four times faster in water than in air.

The speed of sound is influenced by the medium through which it is passing. Water is much denser than air, and this density allows sound waves to transmit energy more efficiently. The molecular structure of water provides a more effective pathway for sound waves to travel, resulting in the increased speed.

This understanding is crucial for divers and those involved in underwater activities, as it affects how sound is perceived underwater compared to above water. Being aware of this difference can help in communication and safety measures while diving.
