There is this thing called the Electromagnetic Spectrum. The wave that makes this radio wave work is called a "Radio wave". Radio waves have the longest wavelength but the slowest frequency understand?
Oh yeah we've been learning this in school
A young girl wonders how the radio on her desk works.
But How do they work??
Oh almost forgot..
1) Electricity flowing into the transmitter antenna makes electrons vibrate up and down it, producing radio waves. 2) The radio waves travel through the air at the speed of light. 3) When the waves arrive at the receiver antenna, they make electrons vibrate inside it
WOW !! That's so cool dad I want to be a scientist when I grow up!
That's Amazing honey! I know you'll change the world!
