What name is given to figures (wave) to indicate that points are attracted to only certain regions in the plane and no to others?
The name given to such figures is "vector fields." Vector fields are used to represent how points in a plane are attracted or repelled by a certain region. One common type of vector field is "attractive" or "repulsive" fields, also known as "source" or "sink" fields. These fields are often represented by wave-like patterns, where the points are attracted to or repelled from specific locations.
To find examples of vector fields indicating attraction or repulsion, you can search for images or illustrations of "source field," "sink field," "vector field attractor," or "vector field repeller" using an internet search engine like Google. You may also find relevant representations in textbooks or educational materials on mathematics or physics.
By studying vector fields and understanding their properties, you can gain insights into various phenomena, such as fluid flow, magnetic fields, and even patterns of social behavior.
