UV radiation has enough energy to break chemical bonds.

Define ultraviolet light. The resulting vacancy affects the chemical properties of the atoms and causes them to form or break chemical bonds that they otherwise would not.

Ultraviolet radiation is electromagnetic radiation or light having a wavelength greater than 100 nm but less than 400 nm. ultraviolet light synonyms, ultraviolet light pronunciation, ultraviolet light translation, English dictionary definition of ultraviolet light. It is also known as UV radiation, ultraviolet light, or simply UV. Definition of Ultraviolet Light.

Ultraviolet (UV) light is a type of electromagnetic radiation that is all around us even though our eyes can't detect it. UV radiation is also produced by electric arcs.

Ultraviolet definition is - situated beyond the visible spectrum at its violet end —used of radiation having a wavelength shorter than wavelengths of visible light and longer than those of X-rays. Ultraviolet. Ultraviolet radiation has a wavelength longer than that of x-rays but shorter than that of visible light. ultraviolet light Electromagnetic radiation of shorter wavelengths than visible light but longer wavelength than X-rays. Jump to navigation Jump to search Portable ultraviolet lamp. Due to their higher energies, UV photons can cause ionization, a process in which electrons break away from atoms. This can be useful for chemical processing, or it can be damaging to materials and living tissues.

Ultraviolet light is divided into three zones—UVA with wavelengths from 380 to 320 nanometres (billionth of a metre), UVB from 320 nm down to 290 nm and UVC from 290 nm down to one tenth of a nanometre. This damage can be b… Ultraviolet definition, beyond the violet in the spectrum, corresponding to light having wavelengths shorter than 4000 angstrom units.
