Question 8 (4 marks) = A step index optical fibre comprises a core of refractive index n1 = 1.448 surrounded by cladding of refractive index n2 1.444 as shown in the figure below. An incident light ray propagates through the fibre via total internal reflection. What is the angle 0 required to ensure that the incident ray undergoes total internal reflection?
