En resumen
The converging lenses are thicker in the middle than at the edge, and concentrate ( they converge ) at a point of light rays through them. This point is called focus (F ) and the separation between it and the lens focal length is known as ( f ) .

converging lenses are thicker in the middle than at the edge, and concentrate (
they converge ) at a point of light rays through them.
This point is called
focus (F ) and the separation between it and the lens focal length is known as
( f ) .
Note that the lens 2 is less than one focal length.
Si miras por una lente divergente da la sensacion de que los rayos proceden del punto F. A este punto se llama foco virtual.
