WebThe electromagnetic spectrum ( EMS) is the general name given to the known range of electromagnetic radiation. Wavelengths increase from approximately 10 -18 m to 100 km, and this corresponds to frequencies decreasing from 3 × 10 26 Hz to 3 ×10 3 Hz. The image below shows the names given to different regions of the EMS. WebMicrowaves are the highest-frequency electromagnetic waves that can be produced by currents in macroscopic circuits and devices. Microwave frequencies range from about 109 Hz to nearly 1012 Hz. Their high frequencies correspond to short wavelengths compared with other radio waves hence the name “microwave.” Microwaves Web14 de nov. de 2014 · Advanced; Basic; The Electromagnetic Spectrum.
