Electromagnetic Spectrum Interactive Presentation
The electromagnetic spectrum is the range of all types of electromagnetic energy: electric and magnetic fields moving together through space. There are both natural and artificial sources of electromagnetic energy. For example, both radio signals and visible light are forms of electromagnetic energy. Radio signals are non-ionising, which means that they cannot directly impart enough energy to a molecule to break or change chemical bonds. This is in contrast to ionising radiation, such as x-rays, which can strip electrons from atoms and molecules.
This interactive presentation provides brief information on the different parts of the electromagnetic spectrum, the type of energy, some applications and safety recommendations.
