Question

1.The core of an optical fiber is made out of a transparent material with a refractive index of 1.50 and the cladding is made out material with a refractive index of 1.44. As shown in the figure, a monochromatic light ray travels in air incident on the one side of the optical fiber and refracted. After that, the refracted ray will enter the core-cladding interface with its corresponding critical angle C. a) Calculate the value of ?? b) Find the range of value for ? where the ray will totally internally reflect through the core-cladding interface? c) When the number of reflections equal to an odd number and even number roughly sketch the outgoing beam through the other side of the optical fiber?
