WebSound waves can be measured according to several different paradigms: amplitude, wavelength, frequency, speed, and, at times, phase. Each of these is associated with certain characteristics, such as loudness and pitch with amplitude; rarefactions and compressions with frequency; distance with wavelength; and elasticity and inertia with speed. WebWe can show sound waves by graphing either how particles move (displacement) or how squished together they are (density). But since density and pressure are related, a pressure vs time graph has the same form as a density vs time graph.
