of wavelengths is known as theelectromagnetic (EM) spectrum. The spectrum is generally divided into seven regions in order of decreasing wavelength and increasing energy and frequency. The common designations are radio waves,microwaves,infrared(IR), visible light, ultraviolet (UV),X-raysandgamma-...
Definition Solar ultraviolet light is ultraviolet light emitted by the sun. Characteristics The sun emits ultraviolet radiation as part of the electromagnetic spectrum. It is usually subdivided, rather arbitrarily, into UVA (400–315 nm), UVB (315–290 nm), and UVC (200–290 nm). UVA has ...

1.2 The Ultraviolet Spectrum The “ultraviolet” is a small portion of the electromagnetic spectrum, yet within its boundaries there are three distinct regions (near, mid, and far UV), each with particular significance in terms of applications and properties. Ultraviolet light is roughly defined as...
Ultraviolet light is a part of the electromagnetic spectrum. Ultraviolet rays have frequencies greater than the frequency of visible light but lower than the frequency of X-rays. The wavelength of ultraviolet light is shorter than visible light and longer than that of X-rays. On interaction with...
While all 3 of these subcategories (UV-A, UV-B, and UV-C) are produced by the sun, the earth’s ozone prevents some UV-B and all UV-C rays from getting through. Since UV-C light is harmful to eyes and skin, direct air and surface disinfection must only be used in unoccupied are...
Ultraviolet (UV) light is electromagnetic radiation with a wavelength that is shorter than visible light and longer than x-rays, emitted at 100 to 400 nanometers (nm). The UV spectrum is divided into: UVA 315 to 400 nm UVB 280 to 315 nm ...
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 radiati
UV-A (315-400nm):The type of ultraviolet light I’ll mostly be focusing on in this particular article is UV-A, which is closest to visible light on the electromagnetic spectrum and is the most popular and is the safest UV light to use. Over-exposure to too much UV-A radiation (wheth...
