A fiber optic cable consists of a glass core surrounded by a layer of material called the cladding further surrounded by a protective cover as shown in the drawing above.If the index of refraction of the core is n1 = 1.50 and the index of refraction of the cladding is n2 = 1.20,what is the critical angle (in degrees)for total internal reflection for light traveling in the core?
