Linear magnification from distance to object and distance to image

Magnification, in optics, the size of an image relative to the size of the object creating it. Depending on the position of the object in relation to the lens, the linear dimensions of the image change.

Notes:

1. If magnfication is positive, the image formed is virtual and erect.

2. If magnfication is negative, the image formed is real and inverted.
