The image formed by a plane mirror is
Correct answer: B. virtual, upright, laterally inverted and the same size as the object
- A. real, inverted and the same size
- B. virtual, upright, laterally inverted and the same size as the object
- C. real, upright and magnified
- D. virtual and diminished
Explanation
The rays only appear to come from behind the mirror, so the image cannot be caught on a screen and is virtual, and it lies as far behind the mirror as the object is in front. Lateral inversion is why writing held up to a mirror reads backwards. The magnification is exactly one.

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.
