Dangers of the em spectrum

WebThe Effect of Frequency. As the frequency of electromagnetic (EM) waves increases, so does the energy. Beyond the visible part of the spectrum, the energy becomes large enough to ionise atoms. As a result of this, the danger associated with EM waves increases along with the frequency. The higher the frequency, the more ionising the radiation. WebA summary of the uses and dangers of different EM waves are summarised in the diagram below: Uses and dangers of the electromagnetic spectrum. Radio Waves & Microwaves. These two parts of the spectrum share a lot of similarities and uses. Their main uses concern wireless communication – in fact many things that people often assume use …
