The greater the distance between the lens and the subject, the greater the angle of view and the lower the magnification

## Which is lens formula?

What is the Lens Formula, and how does it work? It is stated in the Convex Lens equation that the Lens formula is given as 1/f = 1/v + 1/u. It describes the relationship between the Focal Length of a Lens and the distance between an item put in front of it and the picture created by that object.
