For sound waves, the information can be represented on three graphs. Namely: Pressure-distance, Displacement-Distance and Displacement-Time graphs. Since sound waves consist of a series of compressions (high pressure) and rarefactions (low pressure), these information can be represented on a pressure-distance graph. For a displacement-distance graph, you can get the (1) amplitude and (2) wavelength of the sound waves. For a displacment-time graph, you can get the (1) amplitud
