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 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...
Nov 16, 2022 · What is ultraviolet radiation? 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.
When ultraviolet light strikes certain materials, it causes them to fluoresce—i.e., they emit electromagnetic radiation of lower energy, such as visible light.
Apr 1, 2023 · Ultraviolet light that is close to visible light in terms of energy (near ultraviolet UVA and UVB) is non-ionizing radiation. However, energetic (UVC or shortwave) ultraviolet light is ionizing and has an increased capacity to damage DNA and kill cells.
