I don't believe in Radio.  I think it's a made up hoax.

And asking the net a vague question at the last minute virtually guarantees that you won't get good answers until after the homework is due.

If you're in a rush, it is ALWAYS faster to go into a library and ask the reference librarians to help you find an appropriate book.

I've heard that you can get information about radiowaves through radiowaves...<br /><br />Or... The internet (however, if you use WIFI or a cellphone connection...)<br /><br />http://en.wikipedia.org/wiki/Radio_waves<br />

they have the longest wavelength of all the forms of electromagnetic radiation.
they are unaffected by earths atmosphere so radio telescopes can be placed on low altitudes.
cannot be seen by human eyes

Well, radio waves, if I believed in them, can be affected by the atmosphere.  That is the cause of long range radio reception fading in and out. 

Radio waves can reflect off clouds and temperature inversions as well as different levels of the atmosphere.  That's what makes it possible to do long distance communication using 1 watt of power.  Called QRP if you were a ham.

oh i must have misunderstood what i read in the science book, but that happens a lot. the atmosphere has less effect on radio than any other electromagnetic radiation.

I probably didn't get it the first time either.  I relearned some of it when I was working my ham license and fact checked again before I posted just now.

 They are electromagnetic.  They travel the speed of light.  They won't go through metal.  Broadcast radio waves are meters to km in length.
