Black Light

    Hi I was just wondering if black light exists.

    Well, you get these lamps called 'blacklights' that emit nearly no visible light, but mostly in the near ultraviolet range.

    I assume however that you didn't mean those...? If so, no there is no such thing as black light. Black light would be dark, which would be the lack of light.

    Yes, I see it in pictures and movies upon making the color inversion.

    No black lightsabers for the darkside users anytime soon, then? :frown:

    There's no black light in reality, but I know that computer scene-rendering software has an interesting type of beam of non-light that may fit the bill. Pixar has used it in the past. It has most of the properties of a normal beam of light except instead of adding light, it subtracts it. It makes for a very strange effect.

    Certainly. Is made of "darkons" :biggrin:
