... electromagnetic spectrum ... encompasses very short waves (cosmic rays) to light waves (ultraviolet, visible, and infrared) to very long (heat, radio waves, and AC electricity). ... Our environment shows color because of the selective absorption and reflection: A leaf appears green because much of the blue and red in the sun light that illuminates the leaf have been absorbed. Absorption of radiation has many different effects on substances depending on the wavelength of the radiation. Very short wave radiation, such as X-rays and cosmic rays penetrate into the core of an atom and can cause ionization or even nuclear changes.  6, fiche 1, Anglais, - short%2Dwave%20radiation

All objects whose temperatures are above absolute zero emit energy proportional to their temperature. This is called thermal energy. This energy is emitted in the form of electromagnetic radiation whose average wavelength is inversely proportional to the object's temperature. Thus, the hot sun emits short-wave radiation which is mainly UV radiation and visible light; the cooler Earth and atmosphere emit long-wave radiation, which is mainly in the form of invisible light called infrared radiation.  7, fiche 1, Anglais, - short%2Dwave%20radiation

Due to the high temperature of the sun, solar radiation has a short wavelength (hence it is called short-wave radiation) and consists primary of UV radiation and visible light.  8, fiche 1, Anglais, - short%2Dwave%20radiation

En météorologie, le rayonnement est fréquemment subdivisé en rayonnement de courtes longueurs d'onde, inférieures à environ quatre micromètres, d'origine essentiellement solaire, et en rayonnement de grandes longueurs d'ondes supérieures à quatre micromètres, correspondant à l'émission thermique au niveau de la Terre.  3, fiche 1, Français, - rayonnement%20de%20courtes%20longueurs%20d%27onde
