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.
According to Physics Web in 'Sound breaks the light barrier,' a professor of physics in Tennessee has designed an experiment which proves that sound can move faster than light. This looks like impossible -- and it is. In fact, the physicist has tweaked some scientific definitions. No sound can go faster than light. But a sound pulse, or more precisely, all the wavelengths associated to a sound, have a group velocity that far exceeds the real physical limits.
