Derive speed of sound

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 WebMar 7, 2024 · At time t = 0 , the source sends out a sound wave, indicated in black. This wave moves out at the speed of sound v. The position of the sound wave at each time …

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 … 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.
