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.
