What property of fibre cladding keeps light in the core?
AA lower index of refraction
BA higher index of refraction
CA mirrored outer coating
DA thicker outer diameter
Answer & Solution
Correct answer: A. A lower index of refraction
The cladding has a lower refractive index, so light in the core is totally internally reflected.
