TeachMeFinance.com - explain Infrared Radiation Infrared Radiation The term 'Infrared Radiation' as it applies to the area of carbon dioxide can be defined as ' Electromagnetic radiation lying in the wavelength interval from 0.7 micrometers to 1000 micrometers. Its lower limit is bounded by visible radiation, and its upper limit by microwave radiation. Most of the energy emitted by the Earth and its atmosphere is at infrared wavelength. Infrared radiation is generated almost entirely by large-scale intra-molecular processes. The tri-atomic gases, such as water vapor, carbon dioxide, and ozone, absorb infrared radiation and play important roles in the propagation of infrared radiation in the atmosphere. Abbreviated IR; also called 'longwave radiation''. The term 'Infrared Radiation' as it applies to the area of the environment can be defined as 'Radiation emitted by the Earth's surface, the atmosphere and the clouds. It is also known as terrestrial or long-wave radiation. Infrared radiation has a distinctive range of wavelengths ('spectrum') longer than the wavelength of the red color in the visible part of the spectrum. The spectrum of infrared radiation is practically distinct from that of solar or short-wave radiation because of the difference in temperature between the Sun and the Earth-atmosphere system. See radiation, greenhouse effect, enhanced greenhouse effect, global warming'.
