, 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.
UVA rays have the longest wavelengths, followed by UVB, and UVC rays which have the shortest wavelengths. While UVA and UVB rays are transmitted through the atmosphere, all UVC and some UVB rays are absorbed by the Earthâs ozone layer. So, most of the UV rays you come in contact with are UVA with a small amount of UVB. Like all forms of light on the EM spectrum, UV radiation is classified by wavelength.
