By Staff Writer Last Updated Apr 4 2020 92908 AM ET. On the electromagnetic spectrum UV light sits between visible light and X-rays.
We cant see it ourselves though it is present in sunlight and pretty good at damaging our DNA.
Uv light frequency. They are UVA UVB and UVC. Germicidal Efficacy and Mammalian Skin Safety of 222-nm UV Light Radiation Research. What does that mean.
The frequency range of ultraviolet waves is between 75 x 1014 and 3 x 1016 Hertz. The third kind called UVC has. The LED produces a high frequency light either violet or UV and this makes the material fluoresce to produce other colors lower frequency.

This light is why you slather on sunscreen the lotion protects you from two kinds of UV light UVA and UVB which are responsible for premature skin wrinkling sunburns and skin cancers. UV-A - Blacklight UV.
While low there is still some power of a conventional black light in the UVB range. Although black lights produce light in the UV range their spectrum is mostly confined to the longwave UVA region that is UV radiation nearest in wavelength to visible light with low frequency and therefore relatively low energy. According to multiple sources NASA FDA and others here are the wavelengths of the UVA UVB and UVC regions.
The UV spectrum is divided into vacuum UV 40-190 nm far UV 190-220 nm UVC 220-290 nm UVB 290-320 nm and UVA 320-400 nm. For this range the corresponding ultraviolet light wavelengths are 400 to 10 nanometers. 483491 UVC Lamps and SARS-COV-2 International Commission on.
Ultraviolet radiation lies between wavelengths of about 400 nanometres 1 nanometre nm is 10 9 metre on the visible-light side and about 10 nm on the X-ray side though some authorities extend the short-wavelength limit to 4 nm. 280nm - 200nm UV-C Germicidal Ultraviolet at 254nm. Ultraviolet light waves are below the visible light spectrum.
UVA 400 nm - 320 nm UVB 320 nm - 290 nm UVC 290 nm - 100 nm. The type of UV light thats most effective at killing germs like the new coronavirus is UVC light especially far-UVC light which is emitted at a specific wavelength and is less harmful to. 315nm - 280nm UV-B - Dangerous UV.
Since this fluorescent material isnt 100 percent. 200nm - 100nm UV-V - Vacuum UV. UV is divided into three types with reducing wavelengths and increasing energy.
Near 400300 nm middle 300200 nm far 200100 nm and extreme below. To get a little technical ultraviolet UV means beyond violet and refers to a range of electromagnetic waves with a shorter wavelength higher frequency and energy than the visible violet light. In physics ultraviolet radiation is traditionally divided into four regions.
