Ultraviolet (UV) light is electromagnetic radiation of wavelengths of 10–400 nanometers, shorter than that of visible light, but longer than X-rays. UV radiation is present in sunlight, and constitutes about 10% of the total electromagnetic radiation output from the Sun.

Aug 6, 2024 · Ultraviolet (UV) radiation is undetectable by the human eye, although, when it falls on certain materials, it may cause them to fluoresce—i.e., emit electromagnetic radiation of lower energy, such as visible light. Many insects, however, are able to see ultraviolet radiation.

Mar 9, 2016 · Just as visible light consists of different colours that become apparent in a rainbow, the UV radiation spectrum is divided into three regions called UVA, UVB and UVC. As sunlight passes through the atmosphere, all UVC and most UVB is absorbed by ozone, water vapour, oxygen and carbon dioxide.
- Ozone is a particularly effective absorber of UV radiation. As the ozone layer gets thinner, the protective filter activity of the atmosphere is pr...

Aug 10, 2016 · Ultraviolet (UV) light has shorter wavelengths than visible light. Although UV waves are invisible to the human eye, some insects, such as bumblebees, can see them. This is similar to how a dog can hear the sound of a whistle just outside the hearing range of humans.

Nov 16, 2022 · Ultraviolet (UV) radiation is a form of energy that the sun produces. You can’t see UV radiation because its wavelengths are shorter than visible light. The UV energy that the sun produces reaches the Earth and provides vitamin D for your body to help you survive.
Aug 24, 2023 · Ultraviolet (UV) radiation is one part of the electromagnetic spectrum of radiation that reaches Earth from the sun. It is a form of light energy situated on the spectrum just beyond visible...
