Microwaves Essay Example

The discovery of microwaves dates back to 1864, when James Clerk Maxwell predicted their existence. Heinrich Hertz was the first to demonstrate the existence of microwaves in the UHF region in 1888. J.C. Bose also conducted research into the propagation of microwaves and publicly demonstrated radio control using millimeter wavelengths in 1894. Microwaves have an origin in sources such as masers, which function similarly to lasers but use microwaves. Microwaves have various frequency ranges, including super-high, ultra-high, and extremely-high frequencies, which are located towards the start of the electromagnetic spectrum behind radio wavelengths. The wavelengths for microwaves range from 1 mm to 1 m. Microwaves have several uses in communication, including Cable T.V., internet, and mobile phone networks like GSM that use lower microwave frequencies. Satellite communication, such as satellite T.V., direct broadc
