, 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.
It is much the same with radio waves. AM waves bounce off the very large structures involving charged particles in the ionosphere. The shorter wavelength FM waves are better able to see the 'holes' between the ions, and do not really reflect off the ionosphere except for a faint 'ghosting'.
