Ultraviolet

Ultraviolet (UV) light has shorter wavelengths than visible light. Scientists have divided the ultraviolet part of the spectrum into three different regions: 1. the near ultraviolet 2. the far ultraviolet 3. the extreme ultraviolet The three regions are distinguished by how energetic the ultraviolet radiation is, and also by the wavelength of the UV light.

The near ultraviolet (NUV) is the light closest to optical or visible light. The extreme ultraviolet (EUV) is the ultraviolet light closest to X rays, and is the most energetic of the three types. The far ultraviolet (FUV) lies between the near and extreme ultraviolet regions.

It is ultraviolet light that is responsible for causing sunburns. Other negative things that UV light are responsible are genetic damage, cancer, possible eye damage, and also damage to the marine life.

What does it do? Light helps us see and also helps keep us warm but ultraviolet waves carry to much energy. Ultraviolet waves can make electrons get knocked away from an atom. It can also make molecules split. This results in a change in the chemical structure, which this change is especially dangerous for living organisms because it can cause cell damage.
