electromagnetic radiation, energy radiated in the form of a wave as a result of the motion of electric charges. A moving charge gives rise to a magnetic field, and if the motion is changing (accelerated), then the magnetic field varies and in turn produces an electric field Since electromagnetic radiation possesses momentum then it must exert a force on bodies which absorb (or emit) radiation. Suppose that a body is placed in a beam of perfectly collimated radiation, which it absorbs completely. The amount of momentum absorbed per unit time,.

Electromagnetic Radiation. Although the electromagnetic spectrum is made up of many different waves with different properties, they are all electromagnetic radiations. Electromagnetic radiations can be considered as a stream of photons. Photons are particles of zero mass and charge which travel in a wave like pattern at the speed of light radiation (in physics) One of the three major ways that energy is transferred. (The other two are conduction and convection.) In radiation, electromagnetic waves carry energy from one place to another. Unlike conduction and convection, which need material to help transfer the energy, radiation can transfer energy across empty space DESCRIBING ELECTROMAGNETIC ENERGY.
