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
E) from 2 MHz to 80 MHz
Correct Answer: C
Solution :
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 earths atmosphere. These waves can propagate from transmitter to receiver through sky, therefore their propagation is called sky wave propagation.You need to login to perform this action.
