• Electromagnetic waves can bring energy into a system by virtue of their electric and magnetic fields. These fields can exert forces and move charges in the system and, thus, do work on them. If the frequency of the electromagnetic wave is the same as the natural frequencies of the system (such as microwaves at the resonant frequency of water molecules), the transfer of energy is much more efficient
• The energy in any part of the electromagnetic wave is the sum of the energies of the electric and magnetic fields. This energy per unit volume, or energy density u , is the sum of the energy density from the electric field and the energy density from the magnetic field

There is an energy density associated with both the electric field E and the magnetic field B. The rate of energy transport per unit area is described by the vector . which is called the Poynting vector
• EM waves carry energy, momentum and angular momentum away from their source particle and can impart those quantities to matter with which they interact. Electromagnetic radiation is associated with those EM waves that are free to propagate themselves (radiate) without the continuing influence of the moving charges that produced them, because they have achieved sufficient distance from those.
• An electromagnetic wave stores energy in the electric and magnetic fields. You can find the energy density of an electromagnetic wave by calculating the sum of the electric field energy density and magnetic field energy density. An electromagnetic wave transfers energy to the objects in its pat
• The electromagnetic spectrum is the range of frequencies (the spectrum) of electromagnetic radiation and their respective wavelengths and photon energies.. The electromagnetic spectrum covers electromagnetic waves with frequencies ranging from below one hertz to above 10 25 hertz, corresponding to wavelengths from thousands of kilometers down to a fraction of the size of an atomic nucleus
