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. WebElectromagnetic (EM) waves carry energy and so can transfer energy from one point to another point. EM radiation is an energy transfer pathway. EM waves with a shorter wavelength carry a higher energy. This includes UV, X-rays and gamma rays. The higher the energy of the EM wave, the more dangerous it is.
