Hey guys i didn't know how to do this question and figure out the answer, can you help me?
Internet and telephone communications across long distances involve noticeable time delays. The delay is caused by switching latencies and distance. Electrical signals travelling on wires and light signals traveling through fibre-optic cable both travel at about 2/3 of the speed of light. Radio waves traveling through air and space travel at about the speed of light. Using these facts, calculate the following:
a) The time delay for a signal to get across the world (say from here to Egypt) traveling through cables
b) The time delay for a signal traveling across the world via satellite
