Question:
Radio waves in the frequency range 3 MHz – 30 MHz propagate through which mode of propagation?
Radio waves in the frequency range 3 MHz – 30 MHz propagate through which mode of propagation?
Show Hint
Sky wave propagation occurs when radio waves reflect off the ionosphere.
Updated On: Mar 26, 2025
- Surface mode
- Space wave mode
- Sky wave or ionospheric mode
- Ground mode
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Radio waves in the frequency range of 3 MHz to 30 MHz are typically reflected by the ionosphere, leading to sky wave propagation.
