Infrared Radiation

Electromagnetic radiation with a wavelength of approximately 0.7 to 1000 µm that falls between visible red light and microwaves on the electromagnetic spectrum. According to Planck’s law, the solar radiation absorbed by the Earth’s surface is radiated back into the atmosphere in the form of infrared radiation with a wavelength of 8 to 13 µm. This radiation, which warms the atmosphere, especially gases such as water vapor, carbon dioxide and methane, is what causes the greenhouse effect.
