What is Acoustic velocity?

Acoustic velocity refers to the speed at which sound waves travel through a medium, such as air, water, or solids. It is influenced by factors like the medium's density and temperature; for example, sound travels faster in water than in air due to its higher density. The acoustic velocity can be calculated using the formula ( v = \sqrt{\frac{E}{\rho}} ), where ( v ) is the acoustic velocity, ( E ) is the modulus of elasticity, and ( \rho ) is the density of the medium. This property is crucial in fields like acoustics, engineering, and materials science for applications such as sonar and non-destructive testing.
