what are radio waves made of?

Answer 1

All energy that travels through a vacuum with no medium to travel through is called radiated energy. From infrared (not hot enough to see) to gamma rays. Radiated energy is a combination of electronic waves and, at a 90 degree angle, magnetic waves. Each wave creates the other... very interesting. The result is electromagnetic, or EM, radiation.

Radio waves are low in frequency, so LONG in wavelength. "Shortwave" radio has a wavelength (peak to peak) of around 100 feet or 40 meters. By comparison, visible light has a wavelength of about 500 billionths of a meter! But both are forms of EM radiation, different only because of different wavelengths.

Another way of saying different wavelengths is different frequencies. AM radio waves are much lower in frequency than FM radio waves, which are lower in frequency than most TV waves (also EM).

Finally, lower frequencies act more like waves, whereas higher frequencies act more like particles.

Answer 2

the same as all energy in this solar system its a form of light look up the scale for light its listed in the scale from visible light to magnetic or radiation its all light look for this in the ref section of the yahoo encyclopedia it should show it i was at one time a radar operator in the army and micrwave beams are a form of magnetic wave like radio waves just at a differant wavelenght

Answer 3

Radio waves are fluctuating bits of electromagnetic energy

Answer 4

They are light, like visible light, microwaves, and x-rays. Radio waves have very long wavelengths (on the order of a foot or longer), while visible light has wavelenghts of about 500 nm (or 0.000000500 meters).

Answer 5

eletronic energy

Answer 6

electromagnetic radiation.
