ppefmh	Ed	Garstin	2/2	Radio waves are used to transmit radio signals and terrestrial TV signals.	Radio waves are useful for transmitting radio and TV signals because they can travel long distances without being absorbed eg by trees and buildings. Radio waves are useful for transmitting radio and TV signals because they can travel long distances without being reflected eg by trees and buildings. Radio waves are useful for transmitting radio and TV signals because they can travel long distances without being refracted eg by trees and buildings.	Radio waves are reflected off a layer of the atmosphere called the ionosphere. This allows us to send radio signals across very large distances. This is shown in the diagram below.			100%
