b. is always larger
c. can be either bigger or smaller depending on specification
Homework Answers
In optical fiber Electromagnetic wave is transported by using Total Internal Reflection.
Electromagnetic wave is trapped inside core for that Refractive index of core must be greater than that of cladding,If not then the electromagnetic waves will be leaked.
Therfore for the Total internal reflection and for no loss of energy the refractive index of cladding is always smaller
