energy that is transmitted in the form of (electromagnetic) radiation; energy that exists in the absence of matter
Energy traveling in the form of electromagnetic waves. Measured in units of energy such as joules, ergs, or kilowatt-hours.
energy coming to earth from the sun.
Energy from the sun that travels in waves and does not require a medium for its transmission.
laser energy emitted, expressed in joules (J)
Energy which is transmitted away from its source. eg, energy that is emitted when electrons transition down from one level to another.
Any form of energy radiating from a source, such as heat from the sun or a campfire, or light from a bulb.
Measured in watts, reaching a given point accumulated over a given time interval, referred to as joules (watt-sec).
Total energy radiated in all directions. Standard measurement unit J.
energy emitted, transferred, or received in the form of radiation
Radiant energy comes from a light source, such as the sun. Energy released from the sun is in the form of photons. These tiny particles, invisible to the human eye, move in a way similar to a wave. Radiant energy can be transformed into electrical energy using solar panels.
the energy produced by any type of electromagnetic radiation
The energy of any type of electromagnetic radiation. Also called radiation.
Energy that is derived by heat.
Energy traveling as wave motion. Specifically, for electromagnetic waves.
energy (heat) that is transferred by rays or waves, especially electromagnetic waves, through space or another medium. Radiation.
Energy transmitted in wave motion, that is, the electromagnetic spectrum including visible light, ultraviolet, infrared, heat and others.
Energy in the form of electromagnetic waves usually expressed in units of Joules (watt-seconds).
Infrequently, any energy propagated by a physical quantity governed by a wave equation; units are joules.
Energy that transmits away from its source in all directions.
Radiant energy is the energy of electromagnetic waves. The term is most commonly used in the fields of radiometry, solar energy, heating and lighting, but is also used less frequently in other fields (such as telecommunications). The quantity of radiant energy may be calculated by integrating radiant flux (or power) with respect to time and, like all forms of energy, its SI unit is the joule.
