In vector calculus, divergence is a vector operator that measures the magnitude of a vector field's source or sink at a given point, in terms of a signed scalar. More technically, the divergence represents the volume density of the outward flux of a vector field from an infinitesimal volume around a given point.For example:consider air as it is heated or cooled. The relevant vector field for this example is the velocity of the moving air at a point.
