Signals in form of light pulses are fed at one end of an optical fibre of circular cross section of radius r All the rays from the source lie within a cone of half angle 0 measured from the axis of the optical fibre The refractive index of the material of the fibre is u A light pulse lasts for a duration rand two pulses are separated by a time interval At from each other What can be the maximum length of the fibre so that the output pulses are still distinguishable Ans Le cat seco 1 S T At Light Pulses
