In a sound wave the motion of each particle of air is either a simple harmonic motion or a combination of two or more such motions. Though the vibration is longitudinal, the wave may be represented by a curve similar to that in Fig. 1 if we understand that all the particles really move to and fro in the direction of the horizontal line, and that the distances
A, B, etc., above this line represent displacements to the right, and C, D, etc., below the line, displacements to the left. Figure 1 illustrates how such a curve can be drawn.
