Is heat radiation
WebInfrared or red radiation from a common household radiator or electric heater is an example of thermal radiation, as is the heat emitted by an operating incandescent light bulb. Thermal radiation is generated when energy from the movement of charged particles within atoms is converted to electromagnetic radiation. Web1 day ago · Radiation heat is a type of heat transfer that occurs through electromagnetic waves. It is a form of energy that travels through space and can be absorbed or reflected by different materials. Radiation heat is responsible for the warmth we feel from the sun, the heat emitted by a fire, and the warmth we feel from a hot object.
