Question

Which one of the following statements is true about optical fibers?
Select one:
A. Optical fibers uses the concept of total internal reflection to transfer light quickly.
B. The critical angle for total internal reflection in optical fibers is very small because the fiber core is coated with a material with a very low index of refraction.
C. Both A and B is corrected.
D. None of the above is true.
