$Sky wave propagation is suitable for radio waves in which frequency range?$

A. $> 30 MHz$
B. $< 2 MHz$
C. $2 MHz to 30 MHz$
D. $> 300 MHz$

Show correct answer & step-by-step solution

Correct answer: C — $2 MHz to 30 MHz$

Solution

Sky wave propagation relies on the reflection of radio waves by the ionosphere. This method is effective for frequencies in the range of 2 MHz to 30 MHz .
