## Speed of Sound

Speed of sound ( $$a$$ ) 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.

### Speed of Sound Formula

$$a = \sqrt { \frac {K } {\rho} }$$          $$speed \; of \; sound \;=\; \sqrt { \frac { ratio \; of \; specific\; heats } { density } }$$

$$a = \sqrt { k \frac { p } {\rho} }$$          $$speed \; of \; sound \;=\; \sqrt { bulk \; modulus \; \frac { pressure } { density } }$$

Where:

$$a$$ = speed of sound

$$K$$ = bulk modulus

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

$$k$$ = ratio of specific heats

$$p$$ = pressure
