Part of Speech: Noun

Definition: A ground wave is a type of radio wave that travels along or just above the surface of the Earth. It is used for communication, especially for radio broadcasts that need to reach long distances.

Usage Instructions:

• The term "ground wave" is often used in discussions about radio technology, telecommunications, and broadcasting.
• You might encounter it in contexts related to radio frequencies and how signals are transmitted.

Example:

• "The radio station uses ground waves to broadcast its signal to listeners in the surrounding area."

Advanced Usage:

• Ground waves are particularly effective at lower frequencies (like AM radio) because they can follow the curvature of the Earth and can also reflect off the ground, allowing them to travel further than some other types of waves.

Word Variants:

• There are no direct variants of "ground wave," but you might come across related terms like "radio wave" or "surface wave" in discussions about waves and signals.

Different Meanings:

• In different contexts, "ground wave" can refer specifically to radio wave propagation, while in physics, "wave" can refer to other types of waves (like sound waves or water waves).

Synonyms:

• Surface wave (in some contexts)
• Radio wave (though this is a broader term)

Idioms and Phrasal Verbs:
