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.
Its value is measured at 299,792,458 meters per second. Speed of sound on the other hand, is the distance that sound travels through an elastic medium. In dry air with a temperature of 20 Â°C, the speed of sound is measured at 343.2 meters per second. This translates to 1,236 kilometers per hour, or about one kilometer every three seconds. As mentioned previously, the speed of light is denoted by a âcâ, which stands for constant.
