Now consider an object moving at subsonic velocity, V WebSep 12, 2024 · A speaker produces a sound wave by oscillating a cone, causing vibrations of air molecules. In Figure 17.2. 2, a speaker vibrates at a constant frequency and amplitude, producing vibrations in the surrounding air molecules. As the speaker oscillates back and forth, it transfers energy to the air, mostly as thermal energy.

Web47–5 The speed of sound. Our deduction of the wave equation for sound has given us a formula which connects the wave speed with the rate of change of pressure with the density at the normal pressure: c2s = (dP dρ)0. In evaluating this rate of change, it is essential to know how the temperature varies.

WebFor 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.
