If the magnification produced by a lens is +2, then the image is:
General KnowledgePhysics
- Aerect, virtual and smaller than the object
- Binverted, real and smaller than the object
- Cerect, virtual and larger than the object
- Dinverted, real and larger than the object
Explanation
Magnification m is positive (+2), which means the image is erect — it has the same orientation as the object. For a lens, an erect image is always virtual, formed on the same side of the lens as the object. The magnitude |m| = 2 means the image is twice as large as the object. A negative magnification would instead give an inverted, real image. Hence the image is erect, virtual and larger than the object.
