In air at normal atmosphere at 0 oC the speed of sound is 331.2 m/s. The wavelength of a 500 Hz tone can be calculated as. Î» = (331.2 m/s) / (500 Hz). = 0.662 m.
The speed of sound is the distance travelled per unit time by a sound wave propagating through an elastic medium. The SI unit of speed is the metre per second (m/s). In dry air at 20 Â°C, the speed of sound is 343.2 metres per second (1,126 ft/s).This is 1,236 kilometres per hour (768 mph; 667 kn), or a kilometre in 2.914 s or a mile in 4.689 s.he speed of sound is the distance travelled per unit time by a sound wave propagating through an elastic medium.
