11.3 If a signal is sent cross country (3,000 miles) over optical fiber instead of twisted pair wires, how far behind (in seconds) will the electric signal be behind the optical signal? Neglect delays due to amplifiers, repeaters, and so forth. solve for a 2-kHZ sinusoidal signal. Please with steps so I can understand. Thanks
