Question

the core of an optical fibre is fabricated from a material such that relative core-cladding index difference is 0.01.The refractive index of cladding is 1.3.keeping the material of core same,the cladding material is replaced by another medium ,such that core cladding index difference is now 0.02.calculate the ratio of light gathering ability of the optical fibre for the two cases with refractive index of outer medium to be 1.
