The velocity of sound is the speed at which sound waves propagate through a medium, such as air, water, or a solid material. It depends on the properties of the medium, including its density and elasticity. The formula for the velocity of sound in a medium is given by,

Where:

• $v$ is the velocity of sound,
• $B$ is the bulk modulus of the medium,
• $\rho$ is the density of the medium.
