The laser beam can be used to generate three-dimensional objects in a process called:
Correct answer: B. Holography
- A. Iconography
- B. Holography
- C. Logography
- D. Photography
Explanation
Laser beams are used to create three-dimensional images (holograms) through the process of holography, which records and reconstructs light waves to produce a 3D object.

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.
