The speed of sound waves changes depending on what they travel through, like air, water, or solid materials. Let’s take a closer look at what affects how fast sound moves in these different places!
Air: Sound travels slower in air, at about 343 meters per second when it’s 20 degrees Celsius. This is because air is not very dense and can be easily compressed.
Water: In water, sound moves faster—around 1482 meters per second. The molecules in water are closer together, which helps transfer energy quickly.
Solids: Sound can go super fast in solids, reaching speeds over 5000 meters per second! For example, in steel, sound waves can travel about 5960 meters per second, because the particles are packed tightly together and vibrate quickly.
The temperature of the medium is also really important. In air, when the temperature goes up, sound travels faster. This happens because warm air makes the air molecules move faster, so they bump into each other more often.
Density: Usually, when density goes up, sound travels slower in gases. But in solids, more density can sometimes make sound travel faster, especially if the material is elastic.
Elasticity: If a material is more elastic, sound can move faster through it. For example, sound travels slower in rubber than in steel, because rubber is less elastic.
In short, how fast sound waves travel depends on the type of medium, its temperature, density, and elasticity.
