Typical fiber optic communication system uses light of which wavelength
Correct answer: B. 1.3 nm
- A. 1.3 gm:
- B. 1.3 nm
- C. 13 gm:
- D. 13 nm:
Explanation
Reason: Typical fiber optic communication systems use light with wavelengths around 1.3 nm or 1.55 nm. These wavelengths are suitable for efficient transmission through optical fibers with minimal signal loss.

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.
