# Speed of Sound

Written by Jerry Ratzlaff. Posted in Properties

Speed of sound depends on what the medium is and the temperature of the medium. It is the distance traveled for a specific time through a medium from particle to particle.

## formula

$$a = \sqrt { \frac {K } {\rho} }$$

$$a = \sqrt { k \frac { p } {\rho} }$$

Where:

$$a$$ = speed of sound

$$K$$ = bulk modulus

$$\rho$$ (Greek symbol rho) = density

$$k$$ = ratio of specific heats

$$p$$ = pressure
