What is the propagation delay for a signal traveling through a 1000 km cable at a speed of 2 * 10^8 m/s?
Q1. What is the propagation delay for a signal traveling through a 1000 km cable at a speed of 2 * 10^8 m/s?
Answer: 5 ms
Explanation: Propagation delay = distance / speed = 1000 * 10³ / (2 * 10^8) = 5 * 10^-3 seconds or 5 ms.
