The three types of UV radiation are classified according to their wavelength. They differ in their biological activity and the extent to which they can penetrate the skin. The shorter the wavelength, the more harmful the UV radiation The UV region covers the wavelength range 100-400 nm and is...
The Sun is a source of the full spectrum of ultraviolet radiation, which is commonly subdivided into UV-A, UV-B, and UV-C. The typical light source spectrum wavelength ranges from Ultraviolet Light (UV-C: 200 to 280nm; UV-B: 280 to 315nm; UV-A: 315 to 400nm) to Visible Light ...

UV (ultraviolet) radiation: Electromagnetic energy in the wavelength range between 200 and 400 nm. In the solar spectrum on Earth’s surface the wavelength range is limited to 280 and 400 nm. The spectral range is divided in UVC (200–280 nm), UVB (280–315 nm), and UVA (315–400 nm...
UV radiation is subdivided into three wavelength bands: UV-A (315–400 nm) radiation, UV-B (280–315 nm)1 radiation, and UV-C (100–290 nm) radiation. UV-A radiation is largely unaffected by ozone. UV-C comprises less than 0.6% of the incident solar spectrum at the top of the atm...
