Why doesn't it just move forward? • ( 2 votes) The 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 km/h; 767 mph; 667 kn), or one kilometre in 2.91 s or one mile in 4.69 s. It depends strongly on … Visa mer Sir Isaac Newton's 1687 Principia includes a computation of the speed of sound in air as 979 feet per second (298 m/s). This is too low by about 15%. The discrepancy is due primarily to neglecting the (then unknown) effect of … Visa mer The transmission of sound can be illustrated by using a model consisting of an array of spherical objects interconnected by … Visa mer The speed of sound is variable and depends on the properties of the substance through which the wave is travelling. In solids, … Visa mer Speed of sound in ideal gases and air For an ideal gas, K (the bulk modulus in equations above, equivalent to C, the coefficient of stiffness in solids) is given by $${\displaystyle K=\gamma \cdot p.}$$ Thus, from the … Visa mer The speed of sound in mathematical notation is conventionally represented by c, from the Latin celeritas meaning "velocity". For fluids in general, the speed of sound c is given by the Newton–Laplace equation: Visa mer In the Earth's atmosphere, the chief factor affecting the speed of sound is the temperature. For a given ideal gas with constant heat capacity and composition, the speed of sound is dependent solely upon temperature; see § Details below. In such an ideal case, … Visa mer General physical considerations The medium in which a sound wave is travelling does not always respond adiabatically, and as … Visa mer
