Vedclass · Answer

(A) An optical fibre consists of a core and a cladding with different refractive indices. When light enters the core at an appropriate angle,it strikes the core-cladding interface at an angle greater than the critical angle. This leads to the phenomenon of total internal reflection,allowing light to propagate through the fibre with minimal loss.
