what are radio waves?

Question

and how do we receive radio waves?
please keep it simple. otherwise, i won't be able to understand.

Answer 1

Think of radio waves as a form of invisible light. It is an electromagnetic wave that oscillates (pulses) at a frequency that you cannot see.

When radio waves strike a conductor, like the anttenna on your radio, they push electrons around, causing an electric current to flow in the conductor. The radio detects this.

Answer 2

They are electromagnetic waves, like light, with wavelengths between 1 meter and 300 meters in length

Radio waves can be recieved with an antenna, that converts the wave back to an oscillation voltage, that can be amplified
