The process of generating three-dimensional image of the object using laser beam is called:
Correct answer: A. Holography
- A. Holography
- B. Tomography
- C. Scanning
- D. 3-D Cinema
Explanation
Holography is a technique that uses laser beams to create a hologram, which is a three-dimensional image of an object. The other three also create 3D image but they do not involve laser beam.

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.
