Formula speed of sound in air
WebSpeed of sound in a gas is given by the equation: c = γ R T where γ = c p / c v ( c p and c v are specific heats), R is the gas constant, and T is temperature. The specific heat of a gas changes with humidity, so varying these will vary your calculated speed of sound. 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 … See more 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 … See more The transmission of sound can be illustrated by using a model consisting of an array of spherical objects interconnected by … See more The speed of sound is variable and depends on the properties of the substance through which the wave is travelling.
