Optical frequency range

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… WebBoth optical and RF signals are part of the electromagnetic spectrum, with RF having longer wavelengths and lower frequencies than optical signals. The RF part of the electromagnetic spectrum is in the roughly 3 kHz to 300 GHz range, while light (infrared, visible, and ultraviolet) is in the roughly 300 GHz to 30 PHz range.
