How does sound travel in water compared to air?

Sound travels faster in water than in air due to the differences in density and elasticity of the two mediums. In water, sound waves can propagate more efficiently because water is denser and more elastic compared to air. The speed of sound in water is about 1,480 meters per second, while in air it is approximately 343 meters per second at sea level and at room temperature.

The correct answer indicates that sound travels roughly four times faster in water, which is supported by the physics underlying wave propagation. The speed of sound is influenced by the medium's characteristics. Since water molecules are much closer together than air molecules, sound waves can be transmitted more quickly through the medium.

This property is particularly important for divers, as it affects communication and the perception of underwater sounds. Understanding how sound behaves in different environments helps divers anticipate how they will hear underwater compared to on land.
