v = √(γP/ρ)
Where:
* v is the velocity of sound
* γ is the adiabatic index (ratio of specific heats) of the medium. For air, γ ≈ 1.4
* P is the pressure of the medium
* ρ is the density of the medium
Simplified equation for air at room temperature:
For air at room temperature (20°C or 68°F), the speed of sound is approximately:
v ≈ 343 m/s
Important Notes:
* The speed of sound varies depending on the medium and its temperature.
* The adiabatic index (γ) is a property of the medium that reflects how its pressure and volume change during sound propagation.
* The equation above is valid for ideal gases.
For other mediums, the speed of sound may be calculated using different equations.
