What is the difference between shortwave and longwave radio?
Longwave moves along the ground at a certain power and moves across in a linear line. In contrast, shortwave link with the atmosphere and reflects the earth’s path to move in a curve. Longwave comes back to the earth after it gets into the ionosphere. Shortwave too interrelates with the ionosphere.
What is FM MW SW?

Is AM radio shortwave?
It was the first method developed for making audio radio transmissions, and is still used worldwide, primarily for medium wave (also known as “AM band”) transmissions, but also on the longwave and shortwave radio bands. The earliest experimental AM transmissions began in the early 1900s.
