Do anyonw know what colour would semen stains glow under a black light (uv light)?
Someone said BLUE, some said YELLOW.

Would it affected by the wavelength of the black light? (How about a 300-400nm wavelength black light?)

Thanks.

I don't know the colour, but the fluorescence emission from a particular compound is not strongly affected by the input wavelength due to the nature of how fluorescence works: see http://en.wikipedia....blonski_diagram
