Energy stored in electromagnetic waves or radiation. Energy is released when the waves are absorbed by a surface. Any object with a temperature above absolute zero (-273° Celsius) emits this type of energy. The intensity of energy released is a function of the temperature of the radiating surface. The higher the temperature the greater the quantity of energy released.
The energy stored in an electromagnetic field.
Type of energy distinct from chemical energy, kinetic energy, etc. Visible light and radio waves are both forms of electromagnetic energy. See also "Radiation."
Radiant energy emitted by all matter whose temperature is greater than absolute zero (0° K). The warmer the radiant object, the shorter the frequency of electromagnetic waves it emits. Types of electromagnetic waves includes electric currents, heat, radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, x rays, gamma rays, and cosmic rays.
Energy that is reflected or emitted from objects in the form of electrical and magnetic waves that can travel through space.
Energy generated from an electromagnetic field produced by a magnet or an electric current flowing through a conductor.
Energy generated from an electromagnetic field produced by an electric current flowing through a superconducting wire kept at a specific low temperature.
Energy that has both electrical and magnetic characteristics.
The energy in electric and magnetic fields, such as that transported by electromagnetic waves.
The energy of electromagnetic radiation. This may be thought of in a quantum mechanical sense as the sum of all the photon energies composing the radiation, or in a classical sense as the combined energy contained in the oscillating electric and magnetic fields.
Waves of electrical and magnetic energy moving together through space. Also called electromagnetic radiation.
