    A fiber of length 10 cm is illuminated with light from an light emitting diode (LED) which is turned on and off repeatedely for equal amount of time. The speed of the pulse of light are 2.00xx10^(8)m//s and 2.1xx10^(8)m//s in fiber. Maximum frequency of LED os that pulse arrive without overlapping is 60X(KHz) . Calculate X .
