If refractive index of core & cladding are `mu_(1)&mu_(2)` respectively then :

Speed of light through two media of refractive indices mu_(1) and mu_(2) are u_(1) and u_(2) respectively, then

If mu_(1) and mu_(2) are the refractive indices of the material of core and cladding respectively of an optical fiber, then

If mu_(1) and mu_(2) are aboslute refractive index of medium 1 and medium 2 respectively, then

If mu_(1) and mu_(2) are aboslute refractive index of medium 1 and medium 2 respectively, then

The refractive index of the core of an optical fibre is mu_(2) and that of the cladding is mu_(1) . The angle of incidence on the face of the core of that the light ray just under goes total internal reflection at the cladding is

The refractive index of the core of an optical fibre is mu_(2) and that of the cladding is mu_(1) .The angle of incidence on the face of the core so that the light ray just under goes total internal reflection at the cladding is

In optical fibre is refractive index of core greater than cladding or smaller ?

The refractive index of a prism measured using three lines of a mercury vapour lamp. If mu_1,mu_2 and mu_3 are the measured refractive indices for these green, blue and yellow lines respectively, then
