CONVERGING or CONVERGENT Lines, in Geometry, are such as continually approach nearer one another, or whose distances become still less and less. These are opposed to divergent lines, the distances of which become continually greater: those lines which converge one way, diverge the other.

CONVERGING Rays, in Optics, those rays that, issuing from divers points of an object, incline towards another, till at last they meet and cross, and then become diverging rays.

CONVERGING Series, a series of terms or quantities that always decrease the farther they proceed, or which tend to a certain magnitude or limit: in opposition to diverging series, or such as become continually larger and larger.
