Light bulb that emits ultraviolet light; see black light
Light in the ultraviolet part of the spectrum
A form of luminous energy occupying a position in the spectrum of sunlight beyond the violet, and having wavelengths that do not enter the visible spectrum UV rays accelerate deterioration of roof materials Hence, the need for protective coatings
used as a means of detecting fluorescence in gemstones
Light having a shorter wavelength and higher energy than visible light Ultraviolet light is potentially damaging to library, archive and museum objects Removing UV light can reduce the rate of deterioration Certain acrylic sheets have UV filtering chemicals built into them
The portion of the electromagnetic spectrum extending from the violet, or short-wavelength, end of the visible light range to the X-ray region 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
The portion of the electromagnetic spectrum from about 5 - 400 nanometers; this is the form of light responsible for a suntan
Light beyond the visible spectrum
radiation lying in the ultraviolet range; wave lengths shorter than light but longer than X rays
[n] short wavelength light that is beyond the visible spectrum at the violet end; rays of light that are invisible to the human eye but can damage objects
The invisible rays of the spectrum that are outside of the visible spectrum at its short-wavelength violet end Ultraviolet rays are found in everyday sunlight and can cause fading of paint finishes, carpets, and fabrics
These devices shoot UV light at the water to kill bacteria They do not get rid of lead or other minerals, so an activated carbon system is required in addition Ideal for farms, rural homes and cottages where non-chlorinated lake or well water is used
Region of the electromagnetic spectrum spanning wavelengths from 91 2 nm to 350 nm, wavelengths largely blocked by the Earth's atmosphere
Radiant energy with wave lengths slightly shorter than the visible spectrum Found in sunlight, causes color fading
The invisible rays of the sun that penetrate the epidermis and have been proven to cause premature aging and skin cancer
Light that is situated beyond the visible spectrum, at the violet end
Ultraviolet (UV) light refers to particular colors of light which are so blue that most cannot be seen by the human eye UV light from the Sun reacts highly with many chemicals in the atmosphere and controls many aspects of climate and weather UV light also reacts with human skin to cause suntans and sunburns, which can lead to skin cancer
highly energetic part of the electromagnetic spectrum of rays falling between 200 and 400 nanometer wavelengths, which are shorter than that of visible light Carbon arc lamps, black light and mercury vapor lamps are examples of artificial sources of ultraviolet light used by the screen printer
