$\backslash (33\mathrm{.}59\backslash$cdots $0\backslash )$ A fiber$-$optic cable consists of a thin cylindrical core with thickness $\backslash ($ d $\backslash )$ made of a material with index of refraction $\backslash ($ n$\_\{1\}\backslash ),$ surrounded by cladding made of a material with index of refraction $\backslash ($ n$\_\{2\}$

Part C

A typical fiber$-$optic cable has a $50\mathrm{.}0-$mu m$-$thick core with index of refraction $1\mathrm{.}4475$ and has a cladding with index of

refraction $1\mathrm{.}4440.$ What is the minimum radius of curvature for this cable?
