Radio waves are emitted and received by antennas, which consist of conductors such as metal rod resonators. In artificial generation of radio waves, an electronic device called a transmitter generates an AC electric current which is applied to an antenna. The oscillating electrons in the antenna generate oscillating electric and magnetic fields that radiate away from the antenna as ra… WebThe terms " light " and " visible radiation " (VIS) refer to the wavelength range between 400 nm and 800 nm, which can be perceived by the human eye.
