    Dear all,

    What is the meaning of "I wouldn't take a blue
    light to this room" in the following conetxt:

    b: IT SURE IS.

    A: IS THIS A JOKE?

    B: UM, THE ONLY WAY I'M GOING TO BE ABLE TO SLEEP
    IN THIS ROOM IS IF I DOWN A BOTTLE OF JACK. AND I
    MAY NEVER WAKE UP AGAIN. I WOULD NOT WANT TO TAKE

    Re: blue light

    I am *guessing* here.

    In the crime dramas on TV, there is a special light that the investigators use that shows bodily fluids (i.e., semen stains -- though maybe other stuff too) that you can't see in plain light. The person is suggesting that a lot of unsavory things have happened here and it's not very clean.
    I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.

    So blue light can't be translated literally? I don't know, it's clear for you but not for me. What does he mean?

    Re: blue light

    Again, my entire knowledge is based on television shows. The light is actually blue. In some of the shows, they wear special goggles while they shine this blue light around. In some of the shows, the light is actually red or orange or something.

    And I'm still just guessing about the meaning!

    Identification of Semen

    Moreover, as evidenced by the Woods Lamp, or black light technique (23), semen responds to illumination by longer wavelength frequencies of UV light (~ 350 nm) which is invisible to the human eye. When the substance is illuminated, it absorbs the energy and exhibits luminescence at a lower energy (longer wavelength) frequency of visible blue light.


    ...

    2) Long wavelength UV (350 nm) illumination of untreated dry semen produces a more narrow band of emissions centered near the blue visible region.



    3) Illuminating dried semen with a band of visible (450 nm) light produces strong visible fluorescence in a broad region with a maximum around 520 nm (orange).
    UV = ultraviolet

    Re: blue light

    I believe that dermatologists use a blue light to detect certain funguses.

    I know. I tried to access OneLook to see if "funguses" was acceptable, but had trouble doing so. I took a chance, and after freezeframe's post, checked the OALD; they only show "fungi."

    Americans are much more generous. Webster's says fungi or funguses.
