Gam radio signals can usually be heard behind a hill, but fm often cannot. that is, am signals bend more than fm. explain. (radio signals, as we shall see, are carried by electromagnetic waves whose wavelength for am is typically 200 to 600 m and for fm about 3 m.)
I think B, radiant energy
The type of energy that is carried by electromagnetic waves is known as electromagnetic energy. This energy is comprised of a magnetic component and an electrical component. When a magnetic field changes, it creates changes that include an electrical field. Depending on the frequency, this wave can travel long distances and provide radio, wireless Internet, and Satellite transmission, for example.
