revolve; rotate; go around. Context examples: The Earth revolves around the Sun / The lamb roast rotates on a spit over the fire. Hypernyms (to revolve is one way to...): turn (move around an axis or a center) Troponyms (each of the following is one way to revolve): drive in; screw (cause to penetrate, as with a circular motion) screw (turn like a screw)
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 following equations hold true between frequency, wavelength and sound velocity : If the frequency of a sound is 440 Hz (the tone A1) and the velocity of the sound is approximately 330 m/s, its wavelength is 0.75 metres (or 75 centimetres). The successive compressions of the sound wave are 75 centimetres apart. Sound velocity depends on medium (such as metal, water or air) and temperature.
