In a converging lens, the magnification is negative when the object is positioned outside the focal point, indicating that the image is virtual and erect. Conversely, when the object is placed at the focal point, the magnification becomes positive, signifying a real image. This distinction is crucial for understanding the behavior of light in optical systems. For further clarification, refer to the resource provided: HyperPhysics Ray Diagrams.
PREREQUISITESStudents of physics, optical engineers, and anyone interested in the principles of lens magnification and image formation.
Yes (you mean a converging lens). A "negative" linear magnification just means that the image is erect (and virtual).

But in the case where the object is placed in the focal point, then the magnification is "+"?
