Here is a fairly well written general explanation.

Here is one that is a little more complicated.

When Steve answered your question yesterday by asking what did you know that used an antenna, he was referring to radio/TV. TV stations broadcast a signal (both a video signal and an audio signal simultaneously) and these waves are sent through space. They interact with an antenna that is connected to your TV set and the TV set turns that electrical audio and video signal into sound and pictures that are like those that produced them at the station.
The oscillation of electrons in an antenna is an example of which type of radiation/waves/rays?
A. Radio waves
B. Infrared rays
C. Microwaves
D. VLF radiation
I don't understand what is being asked so I don't have a clue on the answer.

I so sorry, it took until know for me to understand what an antenna. I never had to spell it so I didn't know its spelling. After looking at this the answer is A. Right?
I think so. Of course few of us use antennas anymore; most of use use cable or a dish company. The cable sends the signal by wires and the dish on top of our house collects the signal from a satellite.
