Question

The refractive index of core should be … R.I. of cladding in optical filbre ​

Answer 1

Explanation:

The refractive index of the core, n1, is always greater than the index of the cladding, n2. Light is guided through the core, and the fiber acts as an optical waveguide. ... Because the angle of incidence is always equal to the angle of reflection, the reflected light continues to be reflected.

Answer 2

Answer:

The refractive index of the core, n1, is always greater than the index of the cladding, n2. Light is guided through the core, and the fiber acts as an optical waveguide.Because the angle of incidence is always equal to the angle of reflection, the reflected light continues to be reflected.
