WebMicrowaves are the highest-frequency electromagnetic waves that can be produced by currents in macroscopic circuits and devices. Microwave frequencies range from about 10 9 Hz to nearly 10 12 Hz. Their high frequencies correspond to short wavelengths compared with other radio waves—hence the name “microwave.”. WebThey produce microwave beams whose spreading angle is proportional to the ratio of the wavelength of the constituent waves to the diameter of the dish. The beams can thus be directed like a searchlight. Radar beams …
