| − | '''Solar radiation''' is a general term for the visible and near visible (ultraviolet and near-infrared) [[electromagnetic radiation]] that is emitted by the [[sun]]. | + | '''Solar radiation''' is a general term for the [[electromagnetic radiation]] that is emitted by the [[sun]]. While the [[sun]] emits energy at a wide range of frequencies, peak radiance is within the visible range of the spectrum. |
| − | Solar radiation has a spectral, or wavelength, distribution that corresponds to different energy levels. Short wavelength radiation has a higher energy than long-wavelength radiation. | + | Solar radiation has a spectral, or wavelength, distribution that corresponds, roughly, to a black body curve. Short wavelength radiation has a higher energy than long-wavelength radiation. |
