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.
May 31, 2024 · Ultraviolet radiation,that portion of the electromagnetic spectrum extending from the violet, or short-wavelength, end of the visible light range to the X-ray region. Its wavelengths are between 400 and 10 nanometers. Learn more about ultraviolet radiation.
Mar 9, 2016 · Solar emissions include visible light, heat and ultraviolet (UV) radiation. 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.
Nov 16, 2022 · Ultraviolet radiation from the sun is the primary cause of skin cancer, but UV light from tanning beds is just as harmful. Exposure to sunlight during the winter months puts you at the same risk of exposure during the summertime.
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...
Jun 21, 2022 · Skin cancers are caused primarily by exposure to ultraviolet radiation (UVR), either from the sun or from artificial sources such as sunbeds. Globally in 2020, over 1.5 million cases of skin cancers were diagnosed and over 120 000 skin cancer-associated deaths were reported.
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.
