In English, many things are named after a particular country – but have you ever wondered what those things are called in those countries?
- 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.
English has borrowed many of the following foreign expressions of parting, so you’ve probably encountered some of these ways to say goodbye in other languages.
