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

Sound travels significantly faster in water than it does in air due to the differences in density and elasticity between the two mediums. In general, sound moves through water at speeds around 1,500 meters per second, while in air, it travels at approximately 343 meters per second. When comparing these speeds, it becomes evident that sound travels roughly four times faster in water than in air. This is attributed to water being much denser and having greater elasticity, allowing sound waves to transmit more effectively and rapidly. Understanding this concept is crucial for scuba divers, as it influences how they communicate underwater and perceive their environment.
