Well the black light is UV light.So if it is "black" how can it be "light" ?

Its a high frequency low wavelength light.can you see UV? no right? so it appears black.. also its monochomatic that you dont see the tinge of other light or colour...

Pigments that absorb light rather than reflect it back to the eye "look black". A black pigment can, however, result from a combination of several pigments that collectively absorb all colors. If appropriate proportions of three primary pigments are mixed, the result reflects so little light as to be called "black".\n\nThis provides two superficially opposite but actually complementary descriptions of black. Black is the lack of all colors of light, or an exhaustive combination of multiple colors of pigment. \nIn physics, a black body is a perfect absorber of light, but by a rule derived by Einstein it is also, when heated, the best emitter. Thus, the best radiative cooling, out of sunlight, is by using black paint, though it is important that it be black (a nearly perfect absorber) in the infrared as well.\n\nIn elementary science far Ultraviolet light is called "black light" because, unseen (per se), it causes many minerals and other substances to fluoresce.

light.\n\nlet me refer you to e=mc2...light has mass energy and inertia.\na light is a wave and a particle.\nIt is in motion, and objects in motion have inertia and thusly power.\n\nThe true absence of light would exist in a vacuum. There is no pwer in a true vacuum. Even if the absence of light was "massive", that word you chose is a relative term, which is to say that massive CAN NOT imply mass, inertia, etc. The absence of light is NOT measurable because there is nothing there to exist.

Black is not a color. Black is simply the absence of light - what you get when you turn out the light in a room. When you turn off the light switch you don't say, "Look Ma, my room is suddenly painted black." Let me repeat, black is the absence of light, not a color of light.Therefore no light bulb could produce black light. The things that are sold in stores as "black" lights really produce ultraviolet light. Let's switch gears for a second. Imagine you had a piano, but instead of having only 88 keys like a normal piano, it had an infinite number- in other words, it went on forever in each direction. Say you started at middle C and started playing lower and lower keys, toward the left side. Each key to the left causes the corresponding string to vibrate more slowly. Eventually we will come to a key whose string vibrates so slowly that we can't hear the sound. Not because it isn't loud enough but because our ears are not equipped to hear sounds of such low frequency (vibration rates.) For the human this is about 20 vibrations per second. The same applies if we go to the right. The upper limit for humans is about 20,000 vibrations per second. If we hit keys further to the right we would hear nothing. Some animals, dogs for instance, can hear higher frequencies. Now, apply this to light. We can see the results of light frequencies only within a given range. This range is called the visible light spectrum. Think of it as your normal 88 key piano with the key on the far left being labeled red and the one on the far right being labelled violet. Remember Roy G. Biv ? If we go below red, the light is still there but we can't see it because our eyes are not equipped to do so. This invisible light is called infra-red which means below red. Now, to finally get to your question, if we go to the right, higher "keys" than violet produce light that we can't see - not because it isn't there but because our eyes are not equipped to deal with higher frequencies. This light is called ultra-violet meaning above violet. Since to us it isn't there because we can't see it - because to humans it is "absent", or not there, ultra-violet light is sometimes called black light although this name is not really correct. To tie up a few loose ends, most "black" lights in normal price ranges like those you buy at Spencer's, produce a wide range of the spectrum including violet. So you can see them. They do produce some ultra-violet light though and it is the U.V. that causes certain objects to fluoresce (glow.)  Also, just like some animals can hear sounds of higher frequencies than humans some animals, bees for instance, can see ultraviolet light and this ability of bees helps guide them to the source of nectar.

Dark does not push light away, the light is what is moving. Using your example of "over the horizon", the sun (which produces light) moves to the other side of the earth (where we can't see it) then we see dark. But dark does not move, it is just the term we have come up with for what it looks like when there is no light present.

when white light shines on a black object all the constituent colours of white light are absorebed by the body and it appears black

Regular light. It is not a lazer or any special kind of light, just "light". It is probably generated by a specialized piece of equipment, but it is just light - photons. It probably doesn't contain ultra violet light like sunlight, it is probably closer to artificially created light like that from a lightbulb.

use a blacK light and see what happens

Dark is the absense of light.\n\nIllumination is measured in foot candles (in the US anyway) which is roughly equivalent to the amount of illumination created from a candle 1 foot away.

moving from a higher to a lower energy level releases energy, producing light, but;\nit only produces light in the visible light spectrum when it moves down to level n=2.  if it ends up at another energy level, the light released will be infared, ultraviolet, etc... depending on where it ends up.

Its refering to sunlight. Only sunlight goes low or dim (We were afraid that the light was too low)

dark is the absence of light...

It means you have a skin fungus.\nA black light is the way some dermatologists check to see if a skin condition is fungus.\nI am surprised these areas have not bothered you.\nI would get to a dermatologist right away and bring the black light with you to show him in case he does not have one.\nMany dermatologists have black lights to see if a condition is actaully fungus but not all.\nBut hey should all know about the blacklight beieng the test for fungus on the skin.

Light IS energy...sorry I can only think of one...:(

They are water droplets. Huge amount of them will be able to partially block sunlight. So, we see them as being black.

black is the absence of color

no, it is infared light, which is lower energy than regular light. plus it is a very weak, un focused siganl that only transmits for an instant.
