The ground wave consists of which components?

• A. Direct Wave, Ground Reflected Wave, and Surface Wave
• B. Direct Wave only
• C. Surface Wave only
• D. Ground Reflected Wave and Sky Wave

Answer: (A)

The ground wave consists of multiple paths that the radio energy can take to reach the receiver. It includes a direct wave that travels straight through the air from transmitter to receiver, a ground-reflected component formed when part of the energy hits the Earth's surface and reflects upward toward the receiver, and a surface (creeping) wave that travels along the Earth’s surface, hugging the boundary between air and ground and following the curvature of the Earth. The total ground-wave signal is the combination of these three components, which is why all three are listed. The direct and reflected parts alone don’t account for the portion that travels along the surface, and the surface wave alone misses the direct and reflected contributions, so the trio best represents ground-wave propagation.
