Radio waves are a form of electromagnetic energy. Radio receivers interpret this information by converting the frequency (how many cycles of the wave pass a point in a given amount of time) or the amplitude (the strength of a wave). These are called FM and AM radio stations or frequency modulation and amplitude modulation. These waves are often as long as buildings. They are good for broadcasting information because lower frequency waves are usually better at penetrating obstacles like roads, trees and anything between the transmitter and the receiver.

Waves used for broadcastig radio signals are called what?
The waves used to broadcast radio signals are called RF waves and these generally lie in VHF and UHF band of electromagnetic spectrum.
How are radio signals broadcast?
from transmitter through air molecules in the form of waves
What is the difference between broadband and a broadcast?
Broadband involves sending multiple signals on multiple frequencies. Broadcast involves using radio waves also known as electromagnetic radiation to send signals.
How are radio waves and television signals added to EM radio waves?
by changing the amplitude or frequency of the radio waves.
Cell phone signals are transmitted by?
radio waves radiation
Which waves carries AM and FM signals?
Radio waves
How are radio television signals added to EM radio waves?
by changing the amplitude or frequency of the radio waves.
What do baby monitors have to do with Electromagnetic waves?
The monitoring device is a radio transmitter that sends signals to the radio transmitter. Radio waves are a type of Electromagnetic waves.
Are radio waves used to broadcast television programs?
yes
Was the radio named after radio waves or were radio waves named after the radio?
Radio waves were discovered before the radio was invented.
Which EM waves can carry television signals?
Radio waves. Low frequency.
How can radio telescopes be improved?
the radio waves be improved by using the bigger signals
