Sound waves: undulating energy generated by the displacement of molecules causes waves of changing air pressure. Sound waves can move through water and through ground. Sound wave energy has 3 physical attributes produced by the displacement of air molecules. Sound waves fixed speed of 1100 ft/sec. Frequency: the number of cycles a wave completes in a given amount of time. Hertz (hz): sound wave frequencies are measured in cycles per second. Sounds we perceive as low in pitch have slower wave frequencies, whereas sounds that we perceive as high pitched have faster wave frequencies. Many animals communicate with sound: their auditory systems are designed to interpret their species- typical sounds.
