The pattern of so-called "displacement vector" arrows—they have varying lengths (which you can't perceive here) and they point in varying directions—shows the complex fabric motions that we ...

This image depicts the skull's displacement field when a 2000 Hz sound comes from the left side of the head. The arrows indicate both the direction and magnitude of the displacement.

The direction of a vector can be given in a written description, or drawn as an arrow. The length of an arrow represents the magnitude of the quantity. Displacement is the overall distance from a ...
