WebHere, n core and n cladding are the refractive indices of core and cladding, respectively, and n 0 is the refractive index of the medium around the fiber, which is close to 1 in the case of air. Figure 1: An incident light ray is first refracted and then undergoes total internal reflection at the core–cladding interface. However, that works only if the incidence angle is not too … WebThis incident ray travels within the fiber cable to get reflected totally through the interface of core-cladding. However, the incident angle must be more when contrasted to the critical angle or else, if the incident angle is low …
