Which type of fibre is more suitable for transmission of signals in which white light is used?
Correct answer: D. Single mode step index fibre
- A. Monomode step index fibre:
- B. Multimode step index fibre:
- C. Multimode graded index fibre:
- D. Single mode step index fibre
Explanation
Explanation: Single mode step index fiber is more suitable for transmission of signals in which white light is used because it allows only one mode of light to propagate, reducing dispersion effects.

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.
