Question

I read that Sound(waves) travel faster in solids than liquids but also that they travel slower in denser material medium.How is that possible?

Solution

Sound waves travel faster in solids than liquids and travel faster in denser medium.
Sound travels by compression and rare fraction of the medium. In solids or denser medium, particles and very near to each other therefore compression and rare fraction can be done easily. velocity of sound is directly proportional to the elasticity of the medium, solids and denser medium have high elasticity so velocity of sound is more.

Q. Explain, the reason sound propagates faster through metals even though they are denser than gases is that they are stiffer ( i.e., less incompressible). for example: steel is 6000 times denser than air but 2000000 times more elastic than yeah, so sound travel 16 times faster in steel then in air.
