, X-rays X-rays: High frequency electromagnetic radiation, used for medical imaging. , most of the ultraviolet and some of the infrared [infrared radiation: Electromagnetic radiation emitted from a hot object. ] are absorbed by the atmosphere and do not reach the Earthâs surface.ight, some infrared, some ultraviolet ultraviolet radiation: Electromagnetic radiation with a frequency between that of visible light and X-rays. , and microwaves microwaves: Electromagnetic radiation with a frequency between that of visible light and radio waves.
In this case, the substance is the atmosphere. When the atmosphere absorbs energy, the result is an irreversible transformation of radiation into another form of energy. This energy is transformed according to the nature of the medium doing the absorbing. The absorbing medium can also do much more. The medium will only absorb a portion of the total energy.
