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.
Calculate the Speed of Sound in Air vs. Temperature. The velocity of sound can be calculated in metric units as. vms = 20.05 (273.16 + tC)1/2 (1) where. vms = velocity of sound (m/s) tC = temperature (°C) Velocity of sound in Imperial units: vfts = 49.03 (459.7 + tF)1/2 (2) where.
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. You can observe direct evidence of the speed of sound while watching a fireworks display (Figure 17.4).
The speed of sound is affected by temperature in a given medium. For air at sea level, the speed of sound is given by \[v_w = (331 \, m/s)\sqrt{\dfrac{T}{273 \, K}},\] where the temperature (denoted as \(T\)) is in units of kelvin. The speed of sound in gases is related to the average speed of particles in the gas, \(v_{rms}\), and that
the speed of sound is v sound = m/s = ft/s = mi/hr. It is interesting to compare this speed with the speed of molecules as a result of their thermal energy . For the specific example of dry air at 20°C, the speed of sound in air is 343 m/s, while the rms speed of air molecules is 502 m/s using a mean mass of air molecules of 29 amu.

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.
