Medium-wavelength refers to a range of electromagnetic waves that fall between short and long wavelengths. In the context of radio waves, medium-wavelength typically ranges from about 300 meters to 1,000 meters. These waves are often used in AM radio broadcasting, allowing for the transmission of audio signals over long distances. In addition to radio waves, medium-wavelength can also apply to other types of electromagnetic radiation, such as infrared light. This range is important in various applications, including thermal imaging and remote sensing, where it helps detect heat emitted by objects and living beings.
