WebThe frequencies of high frequency microwaves are easily absorbed by food molecules, increasing their internal energy, leading to the food being heated. Microwaves can … WebWhat is the Electromagnetic Spectrum? Scientists have found that many types of wave can be arranged together like the notes on a piano keyboard, to form a scale. The 'low notes' have a low frequency and a long wavelength. The 'high notes' have a high frequency and a short wavelength. When we say "wave", you might think of a wave on the sea.
WebAs a result of this, the danger associated with EM waves increases along with the frequency. The shorter the wavelength, the more ionising the radiation.
