Question

In an optical fiber, the inner core is ------------------ than the cladding

• A. Less Dense
• B. Same density
• C. Denser
• D. None of the option

Answer 1

The correct option is A

Less Dense

Optical fiber

1. The inner core of an optical fiber is less dense than the cladding.
2. Cladding is made up of one or more layers of lower-refractive-index materials that are in close contact with a higher-refractive-index core material. Optical fibers include it. The cladding confines light to the fiber's core via total internal reflection at the interface between the two.
3. This is the fiber's light transmission area, which can be glass or plastic.
4. Cladding: The purpose of cladding is to lower the refractive index at the core interface, causing reflection within the core and allowing light waves to pass through the fiber.
5. The core's refractive index, n1, is always higher than the index.

In an optical fiber, the core is always less dense than the cladding.

Hence, option A is the correct answer.
