(from the article `F-100`) U.S. Air Force jet fighter aircraft, the first operational fighter to exceed the speed of sound in level flight. It was operational from 1953 to ... Once it was recognized that sound is in fact a wave, measurement of the speed of sound became a serious goal. In the 17th century, the French ... The speed of ...

The speed at which small disturbances travel through a medium. In the case of a gas, such as air, the speed of sound is independent of pressure but varies with the square root of temperature. Since temperature decreases with increasing altitude in the atmosphere, so too does the speed of sound; in a...

The speed that a sound wave travels through a given medium. The speed of sound depends on several properties of the medium, most importantly its density. In the atmosphere, the speed changes with air temperature and pressure. At standard sea-level pressure (101.3 kPa), the speed of sound is 340 metres per second (760 mph).

Speed at which sound travels through a medium, such as air or water. In air at a temperature of 0°C/32°F, the speed of sound is 331 m/1,087 ft per second. At higher temperatures, the speed of sound is greater; at 18°C/64°F it is 342 m/1,123 ft per second. It is also affected by the humidity of the air. It is ...
