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.
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.
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...
Jul 29, 2024 · Ultraviolet (UV) radiation covers the wavelength range of 100–400 nm, which is a higher frequency and lower wavelength than visible light. UV radiation comes naturally from the sun, but it can also be created by artificial sources used in industry, commerce and recreation.
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.
Feb 20, 2024 · Ultraviolet (UV) radiation is a form of non-ionizing radiation that is emitted by both natural and artificial sources. There are both benefits and risks to UV radiation. You should always protect yourself from over-exposure to reduce your risk of sunburn, premature aging, and skin cancer.
