Radio waves and microwaves

Royal Corps of Signals

Synopsis

This lesson provides a comprehensive introduction to radio waves and microwaves. Multi-media resources and interactive exercises reinforce understanding of civilian applications and the move towards wireless transmissions. The work of the Royal Corps of Signals, IT and communications providers for the Army, is used to provide an exciting real life context for applications of microwave and radio wave technology, with everyday civilian examples drawn on as well.
