invisible rays in sunlight that cause suntan, sunburn, premature skin aging, and most cases of skin cancer.

type of energy that comes to Earth from the sun and is mostly absorbed by the ozone layer; can cause cancer and other health problems in many types of plants and animals. umbra

Radiant energy with a wavelength just below that of the visible light. UV-c is the shortest wavelength at 200-280nm and is absorbed by the atmosphere before reaching the surface. Extremely damaging to living tissue. UV-b, at 280-315nm is "burning rays" of the sun and is damaging to most living tissue. UV-a, at 315-400nm is &am [..]

electromagnetic radiation of higher frequencies and shorter wavelengths than visible light; UV radiation is divided into three ranges: UV-A (320–400 nm), UV-B (280–320 nm) and UV-C (40–290 nm).

Ultraviolet radiation (UV) refers to high energy rays, in the range of 400–10 nm. UV radiation is invisible to the human eye and comes mainly from the sun.

A form of electromagnetic radiation that is not visible to the naked human eye and which has a wavelength of less than 400 nanometers (nm) and greater than 100 nm. To learn more about this topic click UV Filters.

The portion of the electromagnetic spectrum extending from the violet, or shortwavelength, end of the visible light range to the X-ray region.

One of the kinds of radiation (energy) that comes from the sun. Heat and light are two other kinds of energy radiated from the sun. But ultraviolet radiation contains much more energy than the other k [..]

Invisible electromagnetic radiation with a frequency between that of visible violet light and X rays. Most of the ultraviolet component of sunlight is absorbed by the ozone layer of the atmosphere, bu [..]

Invisible radiation beyond short-wave light (wavelength < 380 nm). Light sources used in architecture usually only emit a limited amount of ultraviolet radiation. Ultraviolet radiation can have det [..]

A specific portion of the sun’s energy that reaches the surface of the earth, specifically, the shortwave, non-visible portion of the electromagnetic spectrum. At elevated levels, ultraviolet radiation can be harmful to plants, animals and humans. The earth’s ozone layer helps to prevent excessive levels from reaching most of the surface of the ear [..]

Solar (shortwave) radiation, the greater part of which is absorbed by stratospheric ozone. Enhanced UV-B radiation suppresses the immune system and can have other adverse effects on living organisms.

The energy range just beyond the violet end of the visible spectrum. Although ultraviolet radiation constitutes only about 5 percent of the total energy emitted from the sun, it is the major energy so [..]

Light energy radiating from the sun that is not visible to the human eye and that can cause sunburn and increase the risk of skin cancer.

Invisible rays that are part of the energy that comes from the sun. Ultraviolet radiation also comes from sun lamps and tanning beds. It can damage the skin and cause melanoma and other types of skin cancer. Ultraviolet radiation that reaches the Earth's surface is made up of two types of rays, called UVA and UVB rays. UVB rays are more likely [..]

The part of sunlight that causes sunburn and skin damage. UV radiation is invisible and does not feel hot. Other sources of UV radiation include solariums, UV lamps and tanning machines.

The energy range just beyond the violet end of the visible spectrum. Although ultraviolet radiation constitutes only about 5 percent of the total energy emitted from the sun, it is the major energy source for the stratosphere and mesosphere, playing a dominant role in both energy balance and chemical composition.
