Most of this emitted radiation is at longer wavelengths than solar radiation. Unlike solar radiation, which is mostly at wavelengths visible to the human eye, the Earth's longwave radiation is mostly at infrared wavelengths, which are invisible to the human eye.
For this reason, solar radiation is sometimes also called shortwave radiation. Most (44%) of the sun's radiation is in the visible wavelengths (0.4 (violet) to 0.7 (red) micrometers). Solar radiation falling outside of this range is not visible to humans, even though it is very intense! The sun's radiation peaks at about 0.5 micrometers, which corresponds to the color blue-green. Red is the longest visible wavelength, and wavelengths longer than 0.7 um are called infrared. Nearly 37% of the sun's radiation is in the slightly longer infrared wavelengths (0.7 to 1.0 micrometers).
