, 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.
This radiative ground wave is known as the Norton surface wave. Other types of surface wave are the non-radiative Zenneck surface wave or ZenneckâSommerfeld surface wave, the trapped surface wave and the gliding wave. See also Dyakonov surface waves (DSW) propagating at the interface of transparent materials with different symmetry.
