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.
Therefore, frequency and pitch should not be considered interchangeable terms. Frequency is directly related to wavelength, often represented by the Greek lambda (). The wavelength is the distance in space required to complete a full cycle of a frequency. The wavelength of a sound is the inverse of its frequency. Example: A440 Hz (the frequency many orchestras tune to) in a dry, sea level, 68Â°F room would create a waveform that is ~2.5 ft. long (2.56 = 1128 (feet/sec) / 440). Be certain to measure the speed of sound and wavelength in the same units.
