Once it has been made clear that photons are quanta of energy, the question becomes 'where does the energy released as IR light from a resistor come from?' And this is not only 100% electronics, in the sense described in the hidden comments, but very specific to the resistor case. … WebbCO2 and H2O absorb a lot of IR radiation because they have internal vibrations with the same energy as infrared photons. ... When the photon is emitted, the molecule loses the energy in that vibration, and the energy is transferred to the photon. Essentially it boils down to conservation of energy. Share. Cite.

WebbInfrared photons do not have enough energy to produce a measurable current with a photon transducer. A thermal transducer, therefore, is used for infrared spectroscopy. The absorption of infrared photons by a thermal transducer increases its temperature, changing one or more of its characteristic properties. One of the most useful applications of the IR spectrum is in sensing and detection. All objects on Earth emit IR radiation in the form of heat. This can be detected by electronic sensors, such as those used in night vision goggles and infrared cameras. A simple example of such a sensor is the bolometer, which consists of … Visa mer Household appliances such as heat lamps and toasters use IR radiation to transmit heat, as do industrial heaters such as those used for drying … Visa mer Caltechdescribes infrared astronomy as "the detection and study of the infrared radiation (heat energy) emitted from objects in the … Visa mer
