प्रश्न
State the factors which limit its range of propagation
उत्तर
Factors which limit the range of propagation:
(a) At frequencies higher than 40 MHz, the space waves scatter more easily and the communication is limited to line-of-sight propagation.
(b) Because of the line-of-sight nature of propagation, direct waves get blocked at some point by the curvature of the Earth.
