Answer

Brief Explanations:

Sky - wave propagation involves the reflection of radio waves off the ionosphere. High - frequency radio waves (3 - 30 MHz) are the ones that reflect off the charged particles in the Earth's ionosphere during sky - wave propagation. Higher frequency waves like UHF, EHF, and microwaves pass through the ionosphere rather than reflecting.

Answer:

High Frequency Radio Waves (3 - 30 MHz)
