What is the range of shortwave frequency?

AM, which stands for Amplitude Modulation (AM) is the oldest radio broadcasting system in the UK . The term AM is commonly used to cover both Medium Wave (MW) and Long Wave (LW). All AM radio stations broadcast in mono.

The name “shortwave” originated during the beginning of radio in the early 20th century, when the radio spectrum was divided into long wave (LW), medium wave (MW), and short wave (SW) bands based on the length of the wave .

shortwave radio, transmission and reception of information by means of electromagnetic waves about 10 to 80 m (33 to 262 feet) in length having frequencies of approximately 29.7 to 3.5 megahertz .
