Question

The electromagnetic waves of frequency 2 MHz to 30 MHz are

• A. In ground wave propagation
• B. In sky wave propagation
• C. In microwave propagation
• D. In satellite communication

Answer 1

The correct option is B In sky wave propagation

The EM waves of frequency from 2MHz to 30 MHz are reflected from the ionized upper layers of earth's atmosphere and hence the sky wave propagation
