Are UV light and UV rays the same thing?
Yes, UV light and UV rays are the same thing, light emit "rays."
How do you get a UV light?
you go to a beauty shop and ask for a UV light
Why do fluorescent light glow when turned off?
Fluorescent lights use electric current to excite mercury atoms, which emit UV light. The tube part of the light is covered in phosphorescent material, which is excited by the UV light the mercury produces, and emits visible light. The reason they glow is because it takes a while for an excited mercury atom to emit the UV light, and it takes even longer for the excited phosphorescent molecules to emit all of their excess energy and return to their normal energy levels, also called the ground state. The path of the energy is Electricity -> UV light-> Visible light-> your eye
Does UV or red light have more energy?
UV light has higher frequency, so it has more energy than red light has
What wavelength of uv light causes thymine dimmers?
UV-c
How does halobacteria protect itself from destruction by UV light?
halobacteria produces salt and chloride layer on top which shortens the UV wavelength protecting itself from UV light. that's why they grow fantastically on Mars.
What is the name of the Vitamin that is absorbed through UV rays?
There is no vitamin that is absorbed through uv rays , but when uv light falls on skin , it produces vitamin D in skin by a photochemical reaction .
How do melanocytes protect skin cells from UV damage?
Melanocytes produces melanin, the skin pigment that absorbs UV light from the sun and prevents it from damaging DNA in the cells.
Is UV light the same as fluorescent light?
The UV light is different to that of fluorescent light. The UV originates from the sun. The latter one does not.No, it is not. UV is different.
Are UV light and UV rays the same thing?
Yes, UV light and UV rays are the same thing, light emit "rays."
How does an ozone lamp work?
"Ozone lamps" are UV light sources that use quartz sleeves between the environment and the mercury plasma that produces the light, and does not have the titanium dioxide coating that absorbs short wave UV and makes lots of visible light (the usual fluorescent light bulb does this). Normal glass will absorb too much of the UV. Ozone in the tropopause is produced by 215nm (or more energetic) UV light, and mercury vapor lamps produce some light at a more energetic 185nm wavelength.
How do you get a UV light?
you go to a beauty shop and ask for a UV light
Is a neon party and a black light party the same thing?
No; a black light or UV light is a light bulb that has a phosphor coating that blocks out nearly all light and produces a dark violet colour and produces UV radiation, this can then be used to make fluorescent,phosphor coated or white coloured objects glow.
Does UV light kill ringworm?
yes the UV light kills the fungus

How is uv light different from light?
It is different because the UV light is brighter then a normal light and it is like a laser. UV light is different to normal light because it is invisible and the wave length is smaller.
Why can UV light cause cancer and not infrared light?
UV light can be turned into infrared light u dofus. DANJUIN
