Outline The electromagnetic spectrum Microwaves Uses of microwaves Why use microwaves

The Electromagnetic Spectrum Radiations travel as waves Types of electron radiation Radio Large wave length Microwaves Infrared Visible light Ultraviolet X-rays Gamma rays Small wavelength

Microwaves Waves are a disturbance in matter Size of microwave from 1 meter to 1 millimeter Grouped into "sub-bands"

Uses of Microwaves C-band penetrate through clouds, dust, smoke, snow, and rain. L-band used in GPS Communication satellites use C-, X-, and Ku-bands Microwaves for heating food

Why use microwaves? Data travels long distances 15 miles up to 4,000 miles Broad band “large amount of data” No need for cables

Thank you
