Section 6 Propagation u Radio waves are electromagnetic waves u How these waves travel from the transmitting antenna to the receiving antenna is called propagation u Radio waves travel in straight lines although they can be reflected, refracted or diffracted u The further the radio wave gets from the transmitting antenna the weaker it becomes u Any time a radio wave travels through anything other than “free Space” it will travel slower and lose strength 24 November 2009 TrainSafe Australia 111
