Question

Which of the following frequencies will be suitable for beyond the horizon communication using sky waves?

Answer 1

Answer:

Sonic boom boom is the right answer

Answer 2

Explanation:

For beyond-the-horizon communication, it is necessary for the signal waves to travel a large distance. 10 KHz signals cannot be radiated efficiently because of the antenna size. The high energy signal waves (1GHz − 1000 GHz) penetrate the ionosphere. 10 MHz frequencies get reflected easily from the ionosphere. Hence, signal waves of such frequencies are suitable for beyond-the-horizon communication.
