How much ultraviolet light reaches earth
NettetUVA is the most abundant and comprises 95% of the UV light that reaches the earth’s surface (i.e. human skin). UVA makes up the majority of indirect UV light that can reach the shade. UVB Rays are also part of the non-visible light spectrum with wavelengths between 280-315nm. NettetThough the size of UV wavelengths ranges from 290 to 400 nanometers, 305 nanometer UV is one of the most damaging wavelengths for humans. Credit: NASA's Goddard …
