In a scanning electron microscope, image formed is:
Correct answer: B. 3D
- A. 2D
- B. 3D
- C. 1D
- D. Any of these
Explanation
A scanning electron microscope (SEM) produces a three-dimensional (3D) image. By using a focused beam of electrons to scan the surface of a sample, an SEM can produce a high-resolution image that provides a wealth of information about the sample's topography, composition, and structure.

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.
