Document Summary
= constant which depends on the gas: transverse waves: when molecules are moved side to side, causing a lateral disturbance to be propagated. Low tension = lower force, waves will propagate more slowly: formula for velocity: Clara rebello: sine waves have three parameters, amplitude: maximum displacement of molecules from one extreme to resting position, periodic vibration: wave repeats itself, frequency (f): Number of cycles per second (hertz hz for short: period (t): time (sec) to complete one cycle, f = 1 / t, starting position/phase: Incompressible fluid: darker grey region is bone. Larger structures respond better to lower frequencies: note: the range at which humans can hear is 20 . If you were to input a pure tone, only one area of the basilar membrane would vibrate. If you were to input a complex tone (consisting of many components), the basilar membrane response is basically the sum of responses for each individual component.
