Transcript of Radio Waves

Microwaves and Radio waves
Radio waves are mostly used in the communication field whereas microwaves are used in industries and astronomy.
X-Rays and Radio waves
X-rays have greater frequency than radio waves
X rays have a shorter wavelength than radio waves
Ultraviolet and Radio waves
UV rays have a higher frequency than radio waves
Radio waves have a longer wavelength
Medical Field
MRI's
Vision correction
treating cancer tumors
Industrial Field
Navigation of ships
Telephones
Garage door openers
About
Low energy waves with long wavelength
Includes FM, AM, radar, and TV waves
Wavelengths of 10^-1m and longer
Low frequency
Used in many devices such as remote control items, cell phones, wireless devices, etc.
Radio Waves
The frequency of radio waves can take values from 300 GHz to 3 kHz, but microwaves are defined to have frequencies ranging from 300 GHz to only 300 MHz.
Radio waves have longer wavelengths than microwaves
Radio waves in general have long distance communication capabilities, but microwaves do not have these abilities.
Microwaves are a sub-class of radio waves.
Ultraviolet radiation is emitted by the sun and are the reason for tans and sun burns
A dentist uses x-rays to get an image of your teeth, and airport security uses them to see through your bags.
