Document Summary

The electromagnetic spectrum: lowest to highest kilohertz, megahertz, and gigahertz, lowest to highest am, shortwave, tv, fm, microwaves. Transduction: the process of changing one form of energy into another: radio broadcasting = changing sound wave energy into electromagnetic wave energy, microphone = transduces/converts air pressure patterns or mechanical waves into electrical patters/waves. Fundamental characteristics of electromagnetic energy: radiate outward from a source without benefit of any discernible physical vehicle, travel at the same high velocity (same speed as light, they have properties of waves. Waves propegate from an antennae like when you drop a rock in a pond. Attenuation: when radio waves lose their energy as they radiate outward (radio/tv: higher frequencies attenuate quicker than lower frequencies, uhf is higher frequency range than vhf. The fcc controls the physical and technical side of radio stations, not the content or programming: controls licenses, assigned frequencies, operating hours, power, antenna height and design.
