UV stands for ultra violet
Because it penetrates the skin and can cause mutations.
There is no such thing. The two are adjacent, in other words, the range for UVB starts where UVA ends.
They don't really have a set design that make them set out from regular lightbulbs. Sometimes it will say on the lightbulb itself. The UVA bulbs I are smaller, longer, and have a narrow end that mushrooms out. More like a tes-tube then a typical lightbulb. It also has a frosted coloring around the sides to aim the rays of light directly down. My UVB bulbs are large and coiled.
It does not. It only absorbs UV-B radiation.
Ultraviolet radiation is a portion of the electromagnetic spectrum with wavelengths shorter than visible light. The sun produces UV, which is commonly split into three bands: UVA, UVB, and UVC. UVA is not absorbed by ozone. UVB is mostly absorbed by ozone, although some reaches the Earth. UVC is completely absorbed by ozone and normal oxygen. see related link
No, they are not the same. A black light bulb produces UVA light.
no,You need both uva and uvb light
Because it penetrates the skin and can cause mutations.
uva
Both UVA and UVB light is used for phototherapy of cutaneous T-cell lymphoma; UVA is usually administered once a week, and UVB can be weekly as well, or sometimes daily.

What is UVA?????
There are three types of rays- UVA, UVB and UVC. UVB and UVA act differently upon our skin and do not equally damage it. The UVB rays are mostly responsible for most cases of sunburn, as they are shorter than UVA rays. The UVA rays are longer so reach the inner state of the skin and causes skin damage.
It should be left on all day, and off all night.
UVA in combination with psoralen is one of the most effective treatment of vitiligo. Psoralen is either used orally or topically and after that skin is exposed to UVA rays which helps in repigmentation.

prickly heat is sometimes a name given to polymorphic light eruptions. this is a primary photosensitivity and it is an allergy to UVA in sunshine. the best way to combat this is to use a 5* UVA filter sun cream
Uva Province was created in 1886.
