What is the difference between radiowaves and microwaves?

Answer 1

The frequency spectrum in which they operate. Microwaves are generally in the ultra high and super high and extremely high frequency bands, e.g., UHF 300 to 3000 MHz and 3000 to 30000 MHz and 30 to 300 GHz, respectively. Thus, radio waves and microwaves can be used to transmit information, as such, they are synonomous. However, radio waves can be generated throughout the electromagnetic spectrum from near 0 Hz to 300 GHz, but are generally considered to be in the frequencies ranges below the infared bands. Microwave is a term used to express electromagnetic energy at higher frequencies. http://en.wikipedia.org/wiki/Radio_waves http://en.wikipedia.org/wiki/Radio_frequency http://imagine.gsfc.NASA.gov/docs/science/know_l1/emspectrum.html http://en.wikipedia.org/wiki/Microwaves
