Question

Which of the following use space wave mode of propagation?

• A. Television broadcast
• B. Microwave
• C. satellite communication
• D. All of the above

Answer 1

The correct option is D All of the above

The radio waves having high frequencies are called space wave. These waves have the ability to travel through atmosphere, this is called space wave mode of propagation. At such high frequencies other method of wave propagation can't work, therefore space wave propagation is used. As television broadcast, microwave and satellite communication all use the high frequency space waves. Hence, all these use space wave mode of propagation .
