Fiber optic cable is in the form of a cylindrical core of fiber with index of refraction 1.67 surrounded by a layer of cladding with index 1.45. Light enters the end of the fiber at an angle of image relative to the fiber’s axis. What is the maximum angle with respect to the axis that light can be incident upon the fiber’s end and be fully transmitted along the fiber thanks to total internal reflection at the fiber/cladding interface?
