Q. The sky wave propagation is suitable for radio-waves of frequency
A) Upto 2 MHz
B) From 2 MHz to 20 MHz
C) From 2 MHz to 30 MHz
D) From 2 MHz to 50 MHz
Explanation
(c) The sky waves are the radiowaves of frequency between 2 MHz to 30 MHz. These waves can propagate through atmosphere but reflected back by the ionosphere of earth’s atmosphere. These waves can propagate from transmitter to receiver through sky, therefore, their propagation is called sky wave propagation.
