Shortwaves refer to radio waves with a wavelength ranging from 10 meters to 1 millimeter. These waves are commonly used in communication and broadcasting systems. Alternative terms for shortwaves include high-frequency (HF) waves, which are commonly used for long-distance communication; microwaves, which are often used in satellite communication and microwave ovens; and ultrashort waves (UHF), which are used for television broadcasting. Other synonyms for shortwaves include high band, decameter band, and meter band. Regardless of what they are called, shortwaves play a vital role in modern communication and technology, enabling people and organizations to connect over long distances.
