Derive speed of sound
WebThe continuity equation in 1d gives you. ρ 0 ∂ t 2 X − ρ 0 C ∂ x 2 X = 0. And this is the wave equation with the speed of sound squared equal to C. … 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.

WebJul 5, 2024 · I think the standard derivation (e.g., Landau Lifshitz vol. 6) is more transparent. All you need to know is that assuming a perfect fluid implies that the … WebThe speed of sound is the distance travelled per unit of time by a sound wave as it propagates through an elastic medium. At 20 °C (68 °F), the speed of sound in air is about 343 metres per second (1,125 ft/s; 1,235 …
WebDec 19, 2024 · First of all, the speed of sound seems to decrease as the mass of the gas increases. But clearly mass is not the only relevant factor. For example, Argon is heavier than Ethane but sound travels more quickly through Argon. The same is true for Neon and Ammonia. How can we make sense of these outliers? WebThe experimental value for the velocity of sound in air at NTP was found to be 332 ms -1. This difference between calculated and experimental value shows the need for some correction in Newton's formula. Later on, Laplace made a correction in Newton's formula now known as Laplace's correction. Velocity of Sound in a Gas: Laplace's Correction.
WebCalculate the velocity of sound at this height using the following equation: v = 4f (H + 0.4D) Results The speed of sound in air is 343 m/s (nearly a mile in 5 seconds!) at 20°C. Compare your experimental value to the true …
