How does density affect the speed of sound?
Answers
As a result, sound waves travel faster in solids than in liquids, and faster in liquids than in gasses. While the density of a medium also affects the speed of sound, the elastic properties have a greater influence on the wave speed.
When speed of the sound decreases with increase in density of the material. The elastic property of the material influences the speed of the sound when it travels through the material. The density of the medium is one of the factors that affects the speed of the sound. The speed of the sound is the fastest in solid. In liquid, the speed of the sound is faster than gas and slower than solid. The sound of the speed is slower in gas compared to solid and liquid. Since the density of the material refers to the arrangement of the molecules in the material and the sound travels with medium. So, the speed of sound increases with density of the material.
