what is radio waves?

Answer 1

Radio waves are electromagnetic waves that have a frequency range of roughly 10 KHz to 300 GHz. The limits are a bit arbitrary: some would put the lower limit at 20 or 30 KHz, or under 10 KHz. Anyway, here's a brief description of what they are...
When an electric current flows through a conductor, a magnetic field is created around it. Likewise, between two oppositely charged particles, there exists an electrostatic field. The magnetic field is created by a flowing current, the electric field, by a potential difference (voltage). If the voltage and current vary at some frequency, the electric and magnetic fields vary at that rate, and form waves--kind of like high/low "stresses" in space--which travel away from the conductor (antenna) that makes them. (The combination electric/magnetic quality gives rise to the term "electromagnetic".) They travel through space, and if they strike another antenna, they induce a voltage and current in it, which can be amplified and demodulated by a radio or TV. This is the quickie explanation. A more detailed description requires a bit of math and physics.

Answer 2

Well radio waves are created by a electrical spark and sent up the antenna to be received by a radio receiver. To better understand this just think of radio waves as you taking a rock and throwing it into a lake and the rock is the electrical pulse and the wave sent out are the ripples in the water! P.S. it should be what are radio waves? I hope this helps and also this is from a stupid truck driver.

Answer 3

Its basically a gravity wave.It would be very elaborate to prove.. but in short that is what it is.
