2. Outline The electromagnetic spectrum Microwaves Uses of microwaves
Why use microwaves

3. 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

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

5. 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

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

7. Thank you
