1(radiation/light/rays) (invariable adjective) ultravioleta
- Most medical lasers emit light which are either ultraviolet, infrared or in the visible spectrum of light.
- Sand on beaches, concrete pavements and snow also reflect up to 40% of the harmful ultraviolet rays.
- Optional Low-E glass coatings help reduce heat and ultraviolet rays that can fade carpet, walls and furniture.
- The bulbs are covered with a plastic screen that helps block out potentially harmful ultraviolet rays that can cause cataracts and skin problems.
- The reason we need sunglasses in the first place is to protect our eyes from the sun's harmful ultraviolet rays.
- Depletion of the Earth's ozone layer is considered responsible for an increase in the solar ultraviolet irradiance reaching the surface.
- They may also be protective in skin conditions attributed to excessive ultraviolet light exposure.
- Finally, the Ultraviolet Imaging Spectrograph, or UVIS, studies wavelengths shorter than humans can see, out to the far ultraviolet.
- Each cluster size emits at a different wavelength, producing ultraviolet, blue, green, red and infrared fluorescence, with the smaller structures being more efficient emitters.
- However, color display as well as camouflage is likely to involve visual signals, ambient light, and/or photoreceptors notably active in the near ultraviolet to which humans are not sensitive.
- This is an ‘enhanced true color’ view spanning ultraviolet to infrared wavelengths.
- The functional significance of vertebrate ultraviolet vision has been the focus of an increasing number of research studies over the last decade.
- It is true that ultraviolet light causes mutations in all living organisms.
- The ultraviolet reflectance of web decorations may play an important role in sensory exploitation.
- Excessive ultraviolet ray exposure can cause premature aging of the skin, cataracts, skin cancers and immune system suppression.
- Investigators assume that ultraviolet light is the most important factor for the initiation of malignant melanoma.
- Diode lasers are now available in discrete colors from the infrared to blue and into the near ultraviolet.
- The liquid materials are photosensitive polymers that solidify when exposed to either laser or ultraviolet light.
- Disinfecting by ozonization or ultraviolet light methods are replacing chlorine in some water treatment plants, but are not yet readily available for home use.
- Damage to the eyes can be prevented by wearing sunglasses with 100-percent ultraviolet blocking.
- Energy reaches earth from the sun in rays of invisible ultraviolet light.
- But what is so special about water that makes its absorptions extend all the way from the far infrared to the near ultraviolet?
- A hat could tell you how much ultraviolet light you're being exposed to.
- Binders must have specific properties such as good adhesion, abrasion resistance, the ability to cure at room temperature, water resistance and ultraviolet light resistance.
- The ultraviolet flash from the supernova explosion, which we first saw 18 years ago, ionized the ring and causes it to glow.
