1. The problem statement, all variables and given/known data A multi-mode fiber optic cable has a core diameter d = 115 mm, ncore = 1.42, and ncladding = 1.17. What is the largest possible angle θin relative to the surface normal that light can enter the fiber (i.e. pass from air into the fiber core) and experience total internal reflection inside the fiber? 2. Relevant equations sinθc=n2/n1 ncladdingθ1=ncoreθ2 3. The attempt at a solution d = 115 mm ncore = 1.42 ncladding = 1.17 θin=? Do I have the correct equations?
