The amount of information that we can convince a radio signal to carry ... and that
we know how to recover from it at the receiving end ... is a certain percentage of
the frequency of the carrier signal. So you see immediately that a higher frequency
carrier can carry more information than a lower frequency one.
A simple everyday example: That's why the music on an FM radio station ... with a
carrier frequency between 88 and 108 MHz ... is higher-fi than the music on an AM
station ... with a carrier frequency between 0.55 and 1.7 MHz.
Microwave radios designed to carry streaming data use carrier frequencies (in
the US) around 6, 11, 18, 23, 38, or 80 thousand MHz , and can carry data at
truly impressive rates that are now approaching a gigabit per second.

__________ transmit signals that carry pictures, data, music and conversations invisibly over long distances and have been the basis for almost all non-written communication and most wireless technologies used by humans today.?
radio waves
How long has Radio Disney been on?
Radio Disney launched in November of 96.
What is radio in French?
J'écoute la radio - I listen to the radio
How long is the average radio show?
It depends on which one.
What is a wireless transmission medium that distributes radio signals through the air over long distances?
Broadcast Radio
Do microwaves carry am signals?
They can - any "radio waves" can carry any kind of modulation, so long's the frequency is a few hundred kilohertz or more - lower frequnecies can be modulated, but the rate of data is so slow it may not be worth the effort.
Which part of the electromagnetic spectrum is nearest to radio waves?
Microwaves and, on the other side, ultra low frequency waves.
Which has higher frequency microwaves or tv waves?
In the entire spectrum of electromagnetic waves, microwaves and radiowaves (microwaves are sometimes classified under radio waves), have the longest wavelengths, and the lowest frequencies (and therefore, energy).
What are the main categories of the electromagnetic spectrum?
short radio waves, long radio waves, microwaves, infrared rays, visible light, ultraviolet rays, x-rays, and gamma rays.
What kind of electromagnetic wave has a wavelength of 1Cm?
That is infra red. Scroll down to related links and look at "Radio and light waves in a vacuum".
Do radio waves have more energy then microwaves?
Nope. Radio waves have a long wavelength, which causes them to carry little energy. For future questions about energy and waves, use the formula E=h(c/lambda). E is the energy of the wave, h is plank's constant, c is the speed of light (3x10^8), and lambda is the frequency. Have fun! ^_^

How were microwaves invented?
Microwaves existed long before the first human being. So they were not invented.
What kinds of waves do satellites use to transmit their locations to global positioning systems?
very short radio waves or long microwaves (1.2-1.6 GHz). It can go either way.
What are some interesting fasts about microwaves?
They are generally used to cook food! but dont look into the microwave for too long while your food is cooking, it can have bad effects to your eyes. on the electro magnectic spectrum they are betweed radio and infrared. microwaves have wave lengths of 10 to the -2 in meters. microwaves are used in cellphones, and thats just off my head im sure there are more facts!.
Is the wavelength of microwave radiation greater than the wavelength of visible light?
Not even close. Microwaves are much longer, with a lower frequency, than light is.The shortest 'microwave' is in the neighborhood of 1 millimeter long (300 GHz).That's about 1,540 times as long as the longest visible wave (red, 650 nm)).
Do microwaves cause any harm?
Microwaves cause radiation, which causes skin cancer...
