How can you see the UV light in laminar air flow otherwise usually you cant see the uv ray?
UV bulbs usually have a coating on the inside that glows when the light is on, providing indication in the visible light part of the spectrum.
What is the wave length of UV?
The wave of UV is shorter then visible light but longer then x-ray waves. It ranges between 400nm and 10nm.
What is a type of ultraviolet ray abbr.?
uv ray dude
What is the wave length of uv waves?
The wave of UV is shorter then visible light but longer then x-ray waves. It ranges between 400nm and 10nm.
Are UV light and UV rays the same thing?
Yes, UV light and UV rays are the same thing, light emit "rays."
When skin is exposed to UV rays is melanin production increased?
Yes!!! The melanin in keratinocytes protects your epidermis and dermis from harmful effects of sun light. Thus, more melanin is produced.
Damaging UV rays of sunlight primary function of what?
In humans, tanning - or sunburn, if you "tan" too much. UV light in excess damages your skin, and your skin reacts by generating melanin pigments in your skin; the melanin causes your skin to get tan. The melanin acts to block the UV light and protect your skin from burns, but too much can make some cancers - "melanomas" - more likely.
What is melanin and where does it come from?
Melanin a group of natural pigments found in most organisms, and is created by the process of melanogenesis. Melanogenesis happens when an organism is exposed to UV radiation. The UV radiation causes the skin to darken (or tan). Melanin effectively absorbs light, and the pigment is able to deplete most (99%) of UV rays that are absorbed.
What is melanin pigment?
Melanin is a pigment produced by cells called melanocytes. This is the pigment which contributes to skin colour. It also provides some protection from UV light.
What cell type and cell product protect the skin from UV irradiation?
The cells in the dermis and epidermis called keratinocytes produce melanin in response to UV light in sunlight.
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.
Visible light x-ray and uv have the same what?
speed
What is the pigment called that protects the body from uv radiation and gives it skin-color?
melanin

What is the mechanism responsible for a suntan?
both the amount and darkness of melanin increase upon UV exposure which gives the skin a tanned appearance. melanin reaction helps protects the body against further UV radiation and prevents damage to DNA.
What is the wave length of UV?
The wave of UV is shorter then visible light but longer then x-ray waves. It ranges between 400nm and 10nm.
Why does skin get dark in the sun but not hair?
Our skin contains melanin. Melanin is a chemical that gets darker due to UV rays. Our hair on the other hand, contains no melanin.
