Optical fibre are based on (a) total internal reflection (b) less scattering (c) refraction (d) less absorption coefficient.

Answer: (a). Light entering the core strikes the core-cladding boundary at more than the critical angle. It is totally reflected again and again and travels along the fibre with very little loss. So the answer is (a) total internal reflection.
