Mar 09, 2016 . The UV region covers the wavelength range 100-400 nm and is divided into three bands: UVA (315-400 nm) UVB (280-315 nm) UVC (100-280 nm). Short-wavelength UVC is the most damaging type of UV radiation. However, it is completely filtered by the atmosphere and does not reach the earth's surface.

The UV index is a measure to help you determine the effects of the sun on outdoor activities. It is computed using forecast ozone levels, cloudiness, and elevation. Values are effective at solar noon, which is when the sun is at its highest point of the day. (Solar noon generally does not correspond to the clock time of 12:00 noon.)

Mar 03, 2022 . The University of the Visayas was founded by the late Don Vicente A. Gullas in 1919 as the Visayan Institute (V.I.) in Cebu City. The second World War razed to the ground the physical facilities of the V.I. at its original site. Undaunted by adversities, Don Vicente reopened classes in Argao, Cebu in 1946.

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.

Q: What is UV Radiation? All radiation is a form of energy, most of which is invisible to the human eye. UV radiation is only one form of radiation and it is measured on a scientific scale called the electromagnetic (EM) spectrum. UV radiation is only one type of EM energy you may be familiar with.
Alternative Titles: UV radiation, ultraviolet light, ultraviolet wave. 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.
The Sun is a source of the full spectrum of ultraviolet radiation, which is commonly subdivided into UV-A, UV-B, and UV-C. These are the classifications most often used in Earth sciences.
What is Ultraviolet Light? UV (Ultraviolet) Light refers to the region of the electromagnetic spectrum between visible light and X-rays, with a wavelength falling between 400 and 10 nanometers.
