no.the only light that can do that is a special light used by the crime investigators and the color of that light is a light purple or light green.
No that is not true its more of any black light which is a purple light not only do the crime investigators have it you can buy it at any store.
yes. Black=absorbs light. That is what black means.
im assuming that u meant "what happens when LIGHT hits a black surface?" the reason for this is that the black surface ABSORBS the light, and so none of the light waves can be reflected back (which is what makes it look black)
it should do objects absorb all light except light of the colour of the object if there is no light of that colour the object appears black
"Black" means "no light". That's why a dark room looks black at niight.If an object really looks black, then you know that it must have absorbed any lightthat hit it, because there's none left to bounce from the object into your eyes.
Blue appears black under a yellow light. For example if you have a blue car and you put a yellow light on it will appear black due to the absence of color. The light has nothing to reflect back.
Yes, a black light will show stains, such as on a carpet or shirt.
Stains don't show so easily.
If you are someone who scratches and stains things easily, I recommend the black Beats By Dre as the stains don't show up much at all on them. However, the white beats do look cooler than the black ones.
ultra violet light will show if its bodily fluids
Yes, If you have a cat that pees on the carpet but you don't know where it is,take the black light and shine it on the carpet it will show the spots where your cat has peed as a light green color.
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..
Yes, fingerprints and other stains show up really well on the black glossy Beats.
yes if it's there Do you need anything else besides a black light?
No, not all black lights are suitable for detecting urine. Black lights that emit ultraviolet (UV) light at a wavelength of 365 nm are ideal for detecting urine stains, as the components in urine will glow under this wavelength. It's important to use the correct type of black light to effectively find urine stains.
Using a black light can help detect semen stains due to proteins in semen reacting to the ultraviolet light. However, for confirmation, additional testing such as a forensic analysis might be needed to definitively identify the presence of semen.
Markers that show under a black light are known as "black light reflective markers", "UV black light reactive", "invisible ink markers", or "black light reflective ink". There are different manufacturers of these items typically available in law enforcement shops, online stores, and sometimes in art stores/departments.
Some black-light tattoos show up in daylight. It depends on how your tattoo is done. Some are done to appear as regular tattoos during the day, and then they look different under black light.
