WOW what a great question...
Yep a black light makes the enzymes & minerals foreign to the flooring Glow at a different rate.. It wont tell you if its semen, just show the pattern & size.. most foreign liquids will glow even after they are dried.. But if your looking for semen or urine, vaginal fluids on sheets, walls, comforter, flooring etc a standard black light will work , the darker the room the better the definition..

What is the wavelenth of black color?
Black is not actually a colour associated with a unique wavelength of light. Black objects absorb nearly all the light at wavelengths our eyes can detect. When we look at something black we are actually seeing 'no light' (or very little compared to the surroundings).White light is the exact opposite; white objects hardly absorb any light. When we look at white objects, our eyes take in light at all wavelengths and we interpret this as the 'colour' white.Visible light wavelength range: 390 to 750 nm (there are 1,000,000 nm in 1 mm)Any light outside this range cannot be seen by humans and could be called 'black'
Why can wavelengths of light be seen by humans?
Our eyes can detect them.

What color of light would detect invisible stains?

If earth and a star were diverging at a combined speed greater than that of light would that star not appear as a black hole?
No. We would be unable to detect it but you can detect black holes(by xrays and light emmitted from material they are sucking up). You would be unable to detect it because if the two were moving away at a combined speed greater than that of light then light from the star could never reach the earth.
