radio wave

Explanation:

Answer 2

Ground wave is a type of radio propagation which is also known as a surface wave. If wave travels directly along the earth from one point to another is called ground wave.

Explanation:

• A surface wave is a mechanical wave that propagates along the interface between differing media.
• In radio transmission, a ground wave is a guided wave that propagates close to the surface of the earth.
• Ground waves are mainly used for transmission between the surface of the earth and the ionosphere.
• These are made up of the number of constituent waves. Low frequencies of the electromagnetic spectrum were used.

• The collection of these radiations along the surface of the earth is known as ground wave propagation.
