An optical cable in-air is orientated horizontally. The cable has a core and a cladding layer. The index of refraction for the core is 1.3 and the index of refraction for the cladding layer is 1.2. A light ray enters the center of the cable with an incident angle a = 58°. The ray is subsequently refracted at the core-cladding interface and the cladding-air interface. The angle between the exit ray and the cable wall is 0. What is the angle e? The index of refraction of air is 1. 1 cladding core degree
