What Is Critical Frequency? |
|
Answer» In SKY wave PROPAGATION, CRITICAL frequency is the limiting frequency at or below which wave is reflected back from the ionosphere, above critical frequency the wave penetrates the ionosphere and NEVER comes back.So for sky wave propagation the VALUE of frequency f≤ fc.
