In optical fibre, refractive index of inner part is 1.68 and refractive index of outer part is 1.44. The numerical aperture of the fibre is

Refractive index of lonosphere is

What is the least radius through which an optical fiber of core diameter 0.05 mm may be bent (as shown in figure) without serious loss of light? The refractive index of the core is 1.6 and that of cladding is 1.5.

The highest refractive index is of :

Assertion : In optical fibre, the diameter of the core is kept small. Reason : This smaller diameter of the core ensures that the fibre should have incident angle more than the critical angle required for total internal reflection.
