Light is nothing but a collection of photons. When some photons hit an object there is 3 possibilities, (i)Reflection, (ii)refraction or complete (iii)Absorption by the object.... When either of this happens you see the object...
For eg if you see an object it is because the light falls on the object and gets reflected based on the refractive index.. that is the reason why you see so many colours that is because when a white light falls on a yellow cloth the cloth absorbs all the colours except yellow and yellow is reflected , as a result you see the cloth as yellow. Same is the case with all colours...
Now let us define darkness.. It may be defined as the state of non-existence of photons..It cannot be called as black photons but absence of photons.. hence technically darkness cannot be called as "Light"
Hope this cleared some darkness from your mind :)

Black Light, term commonly applied to radiation that borders the visible-light region of the electromagnetic spectrum. This includes both long-wavelength ultraviolet radiation and short-wavelength infrared radiation, but most commonly implies the former.

No its pyhsically and technically impossible, as black is the result of our eyes not receiving any light. The reason you see things black is because they do not give off or reflect any light so you see darkness/nothingness

Black light is an oxymoron.It's just a term used to describe something that can be seen under unasual light sourses,and not seen under normal light sourses.

Yes, black light is an solar eclipse of the sun by the moon. The Earth happens to be in the midst of a cosmic coincidence. During a solar eclipse, the Moon perfectly covers the Sun. This is because the Moon moves in a particular orbit that gives it the same apparent size as the Sun when viewed from the Earth.

Ultra-violet light is often called black light.
Ultra-violet light is not normally visible to humans but it causes certain light fabrics and paints to fluoresce making it visible.
Of course it may also be a matter definition.

In Physics, perfect Black Body has been defined as, 100% light absorber. If you have another link to blackness, or you have another definition applying to it. You may have any thing defined like that.

black light is immposible. black is color which absorbs light. black color absorbs 98% of light and doesnt allow to get reflect.
thus if light get reflect then how could our eyes sense it? thus black light is immposible

of coursse darkness is black light
if we switch off the color light then black clor light is automatically
switched on

Not anymore. It was popular in the 70's by drug users till outlawed by the thought police.
