- It is also a ratio between the distance of the image to the distance of the object from the lens. ⇒m=
- If magnification is more than 1, the image is magnified and if it is less than one image is diminished. - If magnification is positive, the image is erect, virtual and if it is negative, the image is inverted, real.
Magnification, m = +2 represents the case of an Enlarged image and hence it must be a Convex Lens.
The image formed by a Convex lens is Erect and Virtual.
Hence the image is erect, virtual, and larger than the object.
