Ones shorter than the other

UV lens coatings are designed to block UV rays from reaching your eyes. Polarized lenses block glare (light reflected off of water or snow, for example) and improve vision that way. Polarized lenses do not offer UV protection - they would need to have a UV coating applied.
One emits light in the ultra-violet range, and the other emits light in the infrared range.
The wavelengths for UV light are shorter than for visible light, but much longer than for x-rays or gamma rays.
UV light is the same as any other kind of light or radiation along the spectrum from radioactive waves to radio waves. The difference between them is their wavelength and fequency. The longer the wavelength, the less the frequency. UV light is high-frequency short-wavelength light, just a bit more high-frequency than the highest-frequency visible light, which is violet. How does light work? Well, even physicists aren't quite sure.
hi, could any one answer what is the difference between hplc uv detector and spectrophotometer uv detector ? my id is debendra_mallick2002@yahoomail.com
Haha
XV is shutoff valve UV is under control valve
flourescence is more sensetive than UV detection
One stabilizes the engine while an absorber absords any excess heat.
technical difference is flow cell is placed in between lamp and optics but in uv it is placed after grating. and flow cell receives monochromatic light in uv detector but polychromatic in pda.
The difference between UV active and inactive compounds is the pi orbitals. Compounds with more pi orbitals are more UV active than those without. Aromatic compounds are generally UV active.
AquaSure Aquaflow Dx is a multi stage UV water purifier whereas AquaSure Storage UV is a 4 stage UV electric water purifier.
The only difference, between ultra violate light and visible light, is their frequencies, UV has higher frequency than visible and since wavelength x frequency = the speed of light (which is constant at 3x108 ms-1), therefore wavelength is higher in UV. UV light is also not visible, unlike visible light! so, in summery the difference is frequency and wave length.

Sun burns are short-term effects. Cancer of the skin could be long-term effects.
