Answer 2

Answer:

find the refractive index n2 of the cladding so that the critical angle at the interface core cladding is 80 degrees

Explanation:

Using the definition of the critical angle, = sin-1(n4/n2)= sin-1(1.44/1.480)= 76.65o. The critical angle for the core-cladding interface is 76.7o. 90o-76.65o= 13.35o> 2.
