If an object is placed away from 2f of a converging lens then the image will be_______________?
Correct answer: C. real and inverted
- A. real and erect
- B. virtual and erect
- C. real and inverted
- D. virtual
Explanation
When an object is placed beyond 2f of a converging lens, the refracted rays meet on the opposite side between f and 2f. The image is therefore real and inverted, and it is smaller than the object. The likely mistake is choosing virtual and erect by confusing a converging lens with a concave lens.

About Optics
Light is studied through reflection, refraction, dispersion, interference, diffraction and polarization, linking ray behavior with its wave nature. Questions may involve mirrors, lenses, optical instruments, refractive index and image formation, while geometrical optics deals with rays and wave optics explains effects such as interference and diffraction.
