Question

Long range propagation is not possible by space wave propagation because

• A. height of troposphere is quite small.
• B. height of troposphere is large.
• C. troposphere absorbs transmitted wave.
• D. None of the above.

Answer 1

The correct option is A height of troposphere is quite small.

Space wave propagation takes place in such a way that the radio waves transmitted at an angle from Earth's surface gets reflected by the troposphere and then reaches the receiving antenna. Since, the height of troposphere is quite small, long-range propagation by this mode is not possible.
