Medium wave refers to a type of radio signal with a frequency range between 530 kHz and 1700 kHz. These signals have a medium wavelength and can travel long distances, especially at night when they can bounce off the Earth's upper atmosphere. Medium wave is commonly used for AM radio broadcasts, allowing stations to reach large areas, though it is more limited in terms of signal clarity and range compared to long wave or short wave. It is still widely used for traditional radio, but has been largely replaced by newer technologies in some regions.Medium wave refers to a type of radio signal with a frequency range between 530 kHz and 1700 kHz.
