Calculate the speed of sound (the sonic velocity) in gases, fluids or solids. A disturbance introduced in some point of a substance - solid or fluid - will propagate through the substance as a wave with a finite velocity.
Determine the speed of sound in different media. Derive the equation for the speed of sound in air. Determine the speed of sound in air for a given temperature. Sound, like all waves, travels at a certain speed and has the properties of frequency and wavelength.
At 0 °C (32 °F), the speed of sound in air is about 331 m/s (1,086 ft/s; 1,192 km/h; 740 mph; 643 kn). [1] The speed of sound in an ideal gas depends only on its temperature and composition. The speed has a weak dependence on frequency and pressure in ordinary air, deviating slightly from ideal behavior.
For helium, γ = 5/3 and the molecular mass is .004 kg/mol, so its speed of sound at the same temperature is. v sound in helium = m/s = ft/s = mi/hr. Doing this calculation for air at 0°C gives v sound = 331.39 m/s and at 1°C gives v sound = 332.00 m/s. This leads to a commonly used approximate formula for the sound speed in air:
