A three-dimensional image of remarkable quality can be achieved by modern version of microscope called:
Correct answer: D. Scanning electron microscope
- A. Compound microscope
- B. Simple microscope
- C. Transmission electron microscope
- D. Scanning electron microscope
Explanation
The Scanning Electron Microscope (SEM) produces high-resolution, three-dimensional images of surfaces by scanning a focused beam of electrons across the sample. The SEM can achieve remarkable image quality, with resolution down to 1-10 nanometers, and a large depth of field, making it ideal for studying surface topography and morphology

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.
