What is the EM Spectrum? • Electromagnetic waves - formed when an electric field couples with a magnetic field • Differ from each other in wavelength • Wavelength - distance between one wave crest to the next
Radio Waves • Longest wavelengths • Longer than a football field or as short as a football • Radio (AM/FM), TV, cell phones
Microwaves • Measured in centimeters • Heat food • Transmitting information from one place to another • Penetrate haze, light rain and snow, clouds, and smoke
