Microwave: Difference between revisions

A '''microwave''' is a high-[[frequency]] [[radio wave]]. They are broadly defined as having a wavelength between 1 millimeter and 1 meter, or narrowly between 3 mm and 300 mm. Microwaves have many uses including [[radar]], [[radio astronomy]], and to heat [[food]] in a [[microwave oven]]. Unlike longer radio waves, they do not bend around land obstacles but go in line of sight. Still, they are much used for [[communication]] because they can have a high [[Bandwidth (signal processing)|bandwidth]]. Almost all [[spacecraft]] communicate by microwave radio.<ref>{{Cite web|title=Microwave Technology|url=https://www.cablefree.net/wirelesstechnology/microwave/|access-date=2021-06-16|website=CableFree|language=en-GB}}</ref><ref name=":0">{{Cite web|title=Microwave radio {{!}} computer science|url=https://www.britannica.com/technology/microwave-radio|access-date=2021-06-16|website=Encyclopedia Britannica|language=en}}</ref>
