Question:
Due to the finite speed of light, it takes some time for a message to be transmitted, especially when communications occur via satellite. Lets see what effect this has. Imagine that youre talking to a friend next door, for which communication is essentially instantaneous if the light or electrons carrying your conversation travels via fiber or wires along a straight line between your nearby homes.
a But, if the light has to travel between the earth and a geosynchronous satellite, km above the earth, how much extra time due to light travel will you have to wait before you hear an answer to your question by your friend?
b Compare this to the time it takes him to think and formulate a response typically less than half a second. Is communication via satellite pleasant or irritating?
