The speed of light in vacuum is sim 3 x 10^8 m/s.

(a) Determine the speed of light inside a fiber with a core refractive index ncore = 1.48.

(b) A light input signal is transmitted from the air trough that fiber and then to the air again. If the source input wavelength used was 1550 nm. what are the frequencies of the signals before (f1) entering the fiber, inside (f2) the fiber and after traversing (f3) the fiber?
