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 basic components of a sound wave are frequency, wavelength and amplitude. In this example of a sound wave, the period of one cycle of this wave is 0.5 seconds, and the frequency of this wave is 2 cycles per second or 2 Hertz (Hz). Click image for larger view.ore specifically, the wavelength of a sound equals the speed of sound in either air or water divided by the frequency of the wave. Therefore, a 20 Hz sound wave is 75 m long in the water (1500/20 = 75) whereas a 20 Hz sound wave in air is only 17 m long (340/20 = 17) in air.
