The frequency suitable for beyond-the-horizon communication using sky waves is

Options

  1. A10 12   Hz
  2. B10 9   Hz
  3. C10 7   Hz
  4. D10 4   Hz

Correct answer

C. 10 7   Hz

Step-by-step solution

The sky wave acts as a radio wave, thus, the suitable frequency suitable for beyond the horizon communication using the sky wave is 10 MHz or (10⁷ ~Hz ) .
