    Describe sky wave propagation in brief.

    Assertion: The surface wave propagation is used for medium frequency and low frequency band. Reason: The attenuation of surface waves increased with increase in frequency.

    Sky wave propagation is also called

    As a wave propagates

    Assertion: The Microwave propagation is better than the sky wave propagation. Reason: Microwaves have frequency 100 to 3001 GHz, which have very good directional properties.
