If the magnification produced by a lens is +2, then the image is :
[amp_mcq option1=”erect, virtual and smaller than the object.” option2=”inverted, real and smaller than the object.” option3=”erect, virtual and larger than the object.” option4=”inverted, real and larger than the object.” correct=”option3″]

The magnification produced by a lens is given by the ratio of the image height to the object height (m = h’/h). The sign of the magnification provides information about the nature and orientation of the image.
A positive magnification (+m) indicates that the image is erect (upright) relative to the object. A negative magnification (-m) indicates that the image is inverted. The magnitude of the magnification (|m|) indicates the size of the image relative to the object: |m| > 1 means the image is larger, |m| = 1 means it’s the same size, and |m| < 1 means it's smaller. A magnification of +2 means the image is erect (due to the + sign) and is twice the size of the object (|2| > 1). For a single lens, an erect image is always a virtual image.
