Mobile phone uses Radio wave or Microwave?

My lecturer said mobile phone uses microwave but I found some web sites and books say radio wave. why is this?


I have been confused...

Mobile phone uses Radio wave or Microwave?
Microwaves are also radiowaves.





Cell phone frequencies do fall in the radio frequency region of 300 MHz to 300 GHz - which is referred to as microwaves.





They're called microwaves because of it's wavelength which falls in the 1mm to 300mm band.





When you drive down the road and you see the high towers with the satellite dishes these are microwave towers for telephone communications.





Microwave ovens use these same frequencies to "cook food", but at much higher power. That's why people were concerned that they may be getting brain damage from using a cell phone alot. Nothing has been proven, but I wouldn't walk around all day with a radio transmitter connected to my ear. Use the earphone/microphone attachment.
Reply:Mobile phones do use Radio Waves- although the border on the EM spectrum between Radio Waves and Microwaves is very fine and difficult to distinguish.


But, yes, you are correct officially mobiles are classed as using radio waves, but your lecturer wasn't entirely wrong as it's a fine line between the two.
Reply:RADIO WAVES!!!


ur teacher MUST be pulling ur leg, my physics teacher was talking about static electriciy, and we were doing an experment with static electricity and our hair. then he came up to me and said "dont doo that too much or else ur hair will fall off! Look at my hair." (and he is almost bald) and i almost BELIEVED HIM!!! i felt rly stupid.





well it is defintly radio waves
Reply:Somd data uses microwave - thats why you see microwave dishes on mobile phone masts. But generally, Lisa is right - its radio waves.

Microwaves are used in microwave ovens.They provide a heating effect.
Reply:Radio waves!! Microwaves heat things up with the mositure that is inside them!!
