Divergence vs Convergence Diagrams - Visual Explanation of Vector Fields #1998006 (License: Personal Use)

The left diagram depicts a source-like behavior where vectors radiate outward uniformly from a central point, representing positive divergence. The right diagram shows a sink-like behavior with vectors converging symmetrically toward the center, indicating negative divergence or convergence. Both are foundational in understanding flux, Gauss’s law, and fluid flow modeling.

Used in educational content on vector calculus, electromagnetism, and fluid mechanics; appears in textbooks, lecture slides, and online STEM tutorials to illustrate field behavior around point sources/sinks.
