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. 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 …
WebJan 18, 2024 · Since a sound wave is a longitudinal wave, we can use this relation to derive the formula for the speed of sound through a medium. Newton assumed that the propagation of sound through a medium is an … WebDerivation of the Speed of Sound in Air As stated earlier, the speed of sound in a medium depends on the medium and the state of the medium. The derivation of the equation for the speed of sound in air starts with …

WebSpeed of Sound The first analytical determination of the speed of sound was given by Isaac Newton in Proposition 49 of Book II of the Principia. For sea level air at a typical ambient temperature he computed a value of 979 ft/sec, which is too low by about 15%, the true value being about 1116 ft/sec. To account for this
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.
